how can i run z test

Lorraine22 — Mon, 24 Apr 2017 14:32:43 GMT

is there a proc to run a z-test in SAS (differencce in proportions); thought there might be since there is proc ttest; else i thought i could modify proc freq or proc uninvariate.

if someone could guide me to SAS documentaiotn on this, would be much appreciated. been searching but can;t find anything.

i did the calc by hand (which was kinda fun); but would be good to know how to do this in SAS

thanks

No, that note is for comparing correlations. See this note for comparing proportions. As noted there, the chi-square test is equivalent to the Z test (just the square of it).

See the article "Test for the equality of two proportions in SAS."
