发帖数: 766 | 1 SAS 9.2 gives a way for noninferioriy test for the difference of two
proprotions.
I try to use that, but confused where to specify the command.
Does anyone use it before ?
here is the link for introduction
http://support.sas.com/documentation/cdl/en/procstat/63104/HTML/default/viewer.htm#procstat_freq_sect010.htm#procstat.freq.binopts
i tried specify in "proc freq" "tables" "test" comond, none of them work.
can anybody like to share the code ?
Thanks in advance! |

发帖数: 766 | 5 sorry to bother again,
in the output, i didn't find p value.
Only CI is given. (i know i can invert it to get SE...lazy to do it ) can we
get non inferiority p value from SAS directly?
proc freq data = a ;
table x * y / riskdiff (noninf margin = 0.05 method = score) ;
run; |
