How to change p-value when running sas code

The default p-value of sas is 0.05. How can i reset the p-value when running the code?

Hello and welcome to the SAS communities 🙂

Please show us the code you are running? Then we can answer your question.

I'd have to disagree with this.

SAS computes the p-value for each test, it does not use 0.05. If the computed p-value is 0.02, then SAS shows 0.02. If the computed p-value is 0.80, then SAS shows 0.80.

So it's not clear what you are doing, or why you say this about p-values.

Hi, Miller,

Thanks for your reply.

Actually, I would like to set p=0.1 when running the sas code. I just figure it out that adding alpha=0.1 will be enough.

Thanks again,

I would like to clarify this.

The p-value is not changed by any ALPHA=0.1 setting that you can specify. The p-value simply is the p-value and there's nothing you can do to change it, that's not a SAS thing, it's true in all software and it's true even if you do the calculations by hand.

ALPHA= only affects hypothesis tests (which may be exactly what you want), but it does not affect p-values.
