Generate F-distribution table

[dan07]

Hello....

I used to use FINV function of Excel to generate tables of values in the f-distribution, taking into consideration different degrees of freedom. I would like ot know if there is a equivalent function in Labview, to do the same operation of FINV of Excel.

Thanks in advance.

There used to be a "F Distribution" VI with LabVIEW 7. This has been replaced by the Continuous CDF function. The MathScript random function also does f-distribution.

Hello smercurio...

I tried what you said but I got no success. I need a function to give me the f-value for any degree of freedom I want. For example: looking at a f-distribution table (P<0.05), I verified that for both degrees of freedom 7, the f value is 3.79. So, I can calculate the f critical value for my data an compare with 3.79.

What I need to feed (x) into the PDF function to get the f value?

The attached example is adjusted to both degrees of freedom 7, but I don't know what x must be.

Thanks

Unfortunately, statistics/probability/stochastic processes was one class in college that I never understood. Very strange. Quantum physics I got. Probability and statistics? No way.

Sorry I can't be of more help.

Does the "Continuous Inverse CDF.vi" do what you want?

I am trying to do the same thing as described in this post.  I see this post was never solved nor can I find anything else that tells me this is even possible in LV.  Are there any current thoughts regarding finding an F-Table value with a known Probability and 2 degrees of freedom.
