P-Test and Z-Test in Windows SAS

deleted_user — Wed, 25 Feb 2009 07:38:31 GMT

Hi,

Does anyone know how to do a P-Test and a Z-Test in Windows SAS?
I know there is a proc ttest which can give you the results directly of a T-Test, but I was not able to find anything for a P-Test and a Z-test.

Also, once the test is done, how do we output this into a table that can be exported into
Excel or Access?

Regards,
Shalini

Perhaps you could enlighten us as to what a P-test is?

A Z-test can be done very simply in a datastep as (Xbar-mu)/sigma, and then you look up the value from the z-table with the SAS function PROBNORM.

You can refer to this link see what is a P-Test :

Also, it would be really helpful if you could send me an example of how to use PROBNORM.

Actually it would be really nice if you could send me a piece of code to do a Z-test in your way

Thanks,

So the p-test is really a p-value? Virtually every SAS statistical procedure produces p-values. Problem solved!

PROBNORM is explained in SAS help, along with an example.

I don't write code for people on the internet ... if you try to write code and can't get it to work, I'll be happy to provide further assistance.
