So you really need to describe what you are testing.</P> Mon, 19 Oct 2020 19:13:43 GMT https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692675#M211044 ballardw 2020-10-19T19:13:43Z Re: What procedure need to use to get unadjusted P values. https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692684#M211056 <P>Almost all procedures will give un-adjusted p values. Please explain your problem in more detail so we can know what you are talking about.</P> Mon, 19 Oct 2020 19:48:34 GMT https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692684#M211056 PaigeMiller 2020-10-19T19:48:34Z Re: What procedure need to use to get unadjusted P values. https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692686#M211058 I am running proc mixed procedure and multitest procedure. I am getting the p-values, So I am curious what is the difference between these p values and unadjusted p values. is there a difference?

You 'adjust' for other variables by then including them in the model, so adding 'age' variable adjusts for the age factor.</STRIKE></P> <P>&nbsp;</P> <P>EDIT: Given the recent update from the OP, this answer is not correct or relevant.</P> Mon, 19 Oct 2020 20:22:23 GMT https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692689#M211061 Reeza 2020-10-19T20:22:23Z Re: What procedure need to use to get unadjusted P values. https://communities.sas.com/t5/SAS-Programming/What-procedure-need-to-use-to-get-unadjusted-P-values/m-p/692691#M211063 <BLOCKQUOTE><HR /><a href="https://communities.sas.com/t5/user/viewprofilepage/user-id/350312">@SASuserlot</a>&nbsp;wrote:<BR />I am running proc mixed procedure and multitest procedure.
