Stationarity test

[girish53]

I would like to use the TSA Stationarity test.vi function available under Signal Processing/Time Series Analysis/Statistical Analysis. I found no documentation or example illustrating its use. I would like to use it on the time series data generated during an experiment. Please let me know where I can find the documentation and/or examples. 

Thank you.

Google is your friend . . .

https://www.ni.com/docs/en-US/bundle/labview-advanced-signal-processing-toolkit-api-ref/page/lvtimes...

Yes, Google was the first thing I tried. Must not have specified the right keywords. 

Thank you for the link. But the directory mentioned on that page TSAGettingStarted is not there on my machine. I am using Labview 2020. Do I need to have the latest version? Would it be possible to send the folder to me? 

The documentation says 'univariate time series data'. What format it expects is not clear.

Thank you.

Reading is your friend.  (Sorry couldn't resist.)  😄

The link clearly shows it's part of a toolkit.  You don't have it installed or you would have the VI and the folder, etc.  Looks like it comes in right under $900 for a 1 year subscription.

Then how is it that I am able to select and add the TSA Stationary Test.vi to the block diagram. I have not used it yet because I am not able to figure out the format in which it needs the input. 

I work for Purdue University and we have a university-wide license to use Labview. The support for Labview is provided by a central IT function. How do I check if I have the required toolkit on my laptop? Is the name of the toolkit Advanced Signal Processing Toolkit?

So I don't understand why you need the folder then?

[girish53]

I need example(s) from the folder. The webpage says to look in TSAGettingStarted directory for example of using TSA stationarity test.

Does this help you find it ?

[girish53]

Thank you. That helped. I was also able to find it in Help|Find Examples...|Toolkits and Modules. I guess I was looking in the wrong place before, and it did not show up in Search.
