Now that we have seen the example of the proc freq used to compute the odds ratio with and without stratification, let's have a look at how to use the logistic regression proc logistic to do it. proc logistic data=dat; weight count; class TRTPN / param=ref ref=last; model ORR(event...

rather than paper, may give more degrees of freedom to the baseline odds. One can derive log-odds-ratio (LOR) of tests from the previous logistic model. Substituting Disease with 1 and 0 in two separate rounds in the model (2), one subtracts the two resulting models. Then some terms ...

I am using proc genmod for logistic regression with repeated measures. However, the following code does not show the odds ratio. I need to know the odds ratio of the continuous variable "rcg00017033 ". proc genmod data=spt_three_final;class studyid ;model spt(event='1')= rcg00017033 ...
Alternatively, a PPOM or NPOM can be fitted through specifying the UNEQUALSLOPES option in the MODEL statement of PROC LOGISTIC starting with SAS software version 9.3 [6]. In biomedical studies, ordinal outcomes may be measured repeatedly on subjects at one or more visits. For example, in a...
greater than 1e-3 and it looks that this is due to calculating p-value. if orpvalue removed from the model statement, this note is not present anymore. Is there any other way to calculate p-value for Odds Ratio with proc logistic or example of how to do this with proc glimmix or ...
