How to get the standard deviation of parameter curve nonlinear

Hello, I tried to understand (as here in the forum) how to obtain the standard deviation for the parameters of a nonlinear curve (Lev - Mar). The most interesting I found was on the Matrix of Covariance. Here the most reliable information came from DSPGuy (Message 8). But in the example VI it first takes the square root of the diagonal elements of the covariance matrix, and then multiplies these values with the RMSE (using the 'appropriateness' VI) to get the standard deviation of the parameters. In the thread, out of time, that it has been said that one has first to multiply the diagonal elements with the MSE directly from the Lev-Mar-VI.

And another question is always there for me. That came in the previous mentioned thread:

What is the DOF?

a: N_MeasPoints - N_FittingParameters

b: N_MeasPoints - (N_FittitngParameters - 1).

If I understand the help for the 'appropriateness' VI a: must also be right, as the DSPGuy States. But I always thought that b: should suit like Peter Vijn2 said in the previously mentioned thread.

Best thanks in advance

Wolfgang

Adding to the Christian post.

1. If our documentation is incorrect, so let's fix it.

2. I checked our source code for the CLN in the goodness of Fit.vi implements the DOF as our States to help.  They agree.  As the Christian States, if a different definition is appropriate for a given application, then you have the option to provide this value for the DOF.  I would add that the results that we return to the example related to the original message of Wolfgang tally with the results that the NIST certifies this problem to 8 decimal places.

3 the form Christian mentioned, old implementation of Lev - Mar had an entry called "gap".  We have mapped to a weight using weight = (1/STD dev.) ^ 2 Christian to map the weight gap is therefore exactly what we used before.

  • How to get the parameter values of a step type custom when I create file and adding a type of step seq

    I use lv 8.5 and teststand 4.0.

    I did a step type custom and recorded at the MyTypes.ini in pallets of type.

    I specified a default module by opening the properties of the custom step of *.ini type window, then I put some values of the parameters.

    T1) when I open teststand and I add the custom step type manaully in seq file, the labview module parameter values are represented.

    But, if to use file (create and add support prototype stage), the labview module parameter values has the default value.

    Using joint file, how to get the setting custom step type values I put in *.ini?

    Q2) each type of step are automatically by name through the use of LoadTypePaletteFilesEx. When I open teststand and I add the custom step type manaully in seq file, the module is loaded automatically. Inside the attachment, I use a prototype of charge and a fixed path where the module labview is to load the labview module.

    Can I load module automatically without using a prototype of charge or how can I get a dynamic path of type step?

    I solved Q1 for myself by using the mapping tab of the parameter within the configuration to the default module window.

    Everyone knows Q2?

  • How to get the parameter

    Hi all
    Greetings!
    I have a requirement in which I need to get the parameter which is recorded in jsp SSWA function.
    for example
    I have a page
    OA.jsp?page=/oracle/apps/conc/webui/ConcPG & Type = XX_DAIL

    Now, I want to use the parameter "LookupType" in my Page CO. processRequest

    I'm trying to get the value of this parameter in processRequest of my CO as

    String l_type1 = pageContext.getParameter ("Type");

    but the string returns NULL when I try to run the jDev page. I'm ideally looking for value "XX_DAIL" in the l_type1 string.

    I have only a single page.

    Please notify.

    Thank you

    I think that since you run it from JDev, you must include the parameter in the configuration of your project (right click on *.jpr--> project settings--> Oracle Applications--> DURATION connection--> the URL parameters in option

    From there, you can specify as: & Type = XX_DAIL

    The co code you must return a value now. Hope it will be useful.

    Kind regards

  • using PostDelayedCall how to get the value passed through void * callbackData?

    Can someone tell me how to get the data passed through void * callbackData?

    The following code, panel_ptr has the right address but still contains zero.

    void CVICALLBACK value_changed (void * callbackData)
    {
    int * panel_ptr;
     
    panel_ptr = callbackData;
    calculate_new_value (* panel_ptr);
    }

    int sign;

    Panel = 2;

    PostDelayedCall (value_changed & Panel, 0.2);

    The problem is using the callbackData parameter if it is a pointer, it must be a pointer to something which is still topical at the moment that the callback executes. That is to say, you cannot pass the pointer to a local variable in callbackData as when the callback executes the pointer is no longer valid. You can switch from its value, instead, in this way:

    ... SomeFunction)

    {

    int sign;

    ...

    Panel = 2;

    PostDelayedCall (value_changed, (void *) Panel, 0.2);

    ...

    }

    void CVICALLBACK value_changed (void * callbackData)
    {
    int panel_ptr;
     
    panel_ptr = (int) callbackData;

    calculate_new_value (panel_ptr);

    return;
    }

    There are many discussions on the forums on callbackData parameter that you might want to read.

  • How to get the bar display of title in pixels text length?

    Hello

    Does anyone know how to get the length of the title bar text (in pixels) display?  Just to clarify, that's what I'm looking for:

    I don't see a CVI function for this.  The attribute ATTR_TITLE_FONT for GetPanelAttribute (...) is only valid for the panels of the child which prevents me from using the GetTextDisplaySize (...) to get the size.  Dive into the Windows SDK I can not even find an answer here.  Any ideas?  Thank you.

    Figured out how to do this.  Go to the SDK to get the font properties - is kind of nonobviousness.  But once you have the font properties, you can create a font of meta in CVI, with properties, and once you have the meta font you can use GetTextDisplaySize (...) to get the size.  For any future reference:

    //define a NONCLIENTMETRICS structureNONCLIENTMETRICS ncmtest;//We have to set the cbSize parameter to the size of the passed structure before retrieving it
    ncmtest.cbSize = sizeof(NONCLIENTMETRICS);
    //Get NONCLIENTMETRICS structure
    result = SystemParametersInfo(SPI_GETNONCLIENTMETRICS, 0, &ncmtest, 0);
    
    //copy the title font name to a c-string
    while(ncmtest.lfCaptionFont.lfFaceName[i] != 0)
    {
        thefont[i] = (char)ncmtest.lfCaptionFont.lfFaceName[i];
        ++i;
    }
    
    //null terminate
    thefont[i] = '\0';
    
    //create meta font with title font properties.  lfWeight & 0x700 indicates bold.  CreateMetaFontWithCharacterSet() doesn't recognize DEFAULT_CHARSET so we replace it with VAL_NATIVE_CHARSET(?).
    uir_status = CreateMetaFontWithCharacterSet ("TheTitleFont", thefont, abs(ncmtest.lfCaptionFont.lfHeight), ncmtest.lfCaptionFont.lfWeight & 0x700 ? 1 : 0, ncmtest.lfCaptionFont.lfItalic, ncmtest.lfCaptionFont.lfUnderline, ncmtest.lfCaptionFont.lfStrikeOut, 0, ncmtest.lfCaptionFont.lfCharSet == DEFAULT_CHARSET ? VAL_NATIVE_CHARSET : ncmtest.lfCaptionFont.lfCharSet);
    
    //get titlebar text
    uir_status = GetPanelAttribute (panelhandle, ATTR_TITLE, thetext);
    //get title bar length
    uir_status = GetTextDisplaySize (thetext, "TheTitleFont", &height, &width);

    Hi all

    I have a problem when I want to export the settings of the effect.

    (I checked the sample project "ProjDumper").

    Yellow: layer

    Red: one of the effect (text)

    Green: the parameters of the effect (I want to export these values).

    Here is my code:

            // 1. use a loop to find the "Text" effect
         // 2. get all the params from this effect
         A_long iL = 0;

         AEGP_StreamRefH streamH = NULL;
         AEGP_EffectRefH effectH = NULL;
         PF_ParamType            param_type;

              {
                   AEGP_InstalledEffectKey     key;

                   ERR(Suites.EffectSuite2()->AEGP_GetEffectName(key, effect_nameC));
    
                   if (!strcmp(effect_nameC, "Text")) 
                   {
                        // Get number of effect parameters from Text effect
                        ERR(Suites.StreamSuite2()->AEGP_GetEffectNumParamStreams(effectH, &num_paramsL));
    
                        for (jL = 1; jL < num_paramsL; ++jL) // start at 1 to skip initial layer param

    In the SDK document, it indicates the value of PF_ParamDefUnion should not be used.

    So, how can I get these params in the effect, I put (the green line on the photo)?

    And, if there is any harm in my logic, please let me know.

    Thank you.

    > How do I know what setting is pop-menu, checkbox, or difficulty slider? (You can see the green line in the picture).

    I now just how to get the stream parameter type (type of AEGP_StreamVal: AEGP_OneDVal, AEGP_ColorVal etc.). Pop-up menu, checkbox or fix cursor parameter streams have the same type of workflow: AEGP_OneDVal.

    How to control parameter type you already posted in your code).

    > Shouldn't use a loop to get all the params?

    I also use this loop...

    > Could you please tell more in detail how to use it?

    I don't know what you want to do... I can't say more as written in the SDK.

    You can find information about schema objects in eTRM Web site, you can also consult the documentation for product/module and see if it helps. If you already have any report (standard or custom), you can enable the trace and run the program to see which object it access or open the report using Report Designer and see the code.

  • How to get the text have the same effect as the video?

    Hello

    For the first time post here, but I wonder how to get the text of the titles have the same effect as the video behind her.

    For my video, I use 'bad tv' and other effects such as Gaussian that obviously changes the appearance of video, creating the look of VHS. However, I then inserted text via the title, but it normally appears. How can I make this text have the same effects as the video behind it?

    A friend told me I might need to add text to the video first, then do the effects, I have not tried, but wonder if there is an easier way, as this would require me to restart.

    EDIT: That's what I'm looking for. https://youtu.be/7_2PHQI89dI?t=24s The text has the same effect as the video.

    Thank you

    One way is to create a clip made up based on the title and the original clip. Then apply the effect.

    Another way is to use an adjustment layer.

    Good luck.
