The INEST= option on the PROC LOGISTIC statement names the data set that contains initial parameter estimates for starting the iterative ML estimation algorithm. The MAXITER= option in the MODEL statement specifies the maximum number of iterations to perform. The combination of DATA=validation data, ...
SAS中的离散被解释变量模型:PROC LOGISTIC和PROC GENMOD 最简单的离散被解释变量模型就是logit了,在SAS里面有直接的PROC LOGISTIC。官方文档在此:http://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/viewer.htm#logistic_toc.htm 语法自然是一如既往的简单:proc logistic; model y=x1 x2; ru...

If you have the numerator and denominator counts in each of the rates, then you can use the events/trials syntax for the response in the PROC LOGISTIC MODEL statement. You can then use the general method in this note to compare slopes among the groups. You would then have cod...
For example, this can be done in the MODEL statement of PROC LOGISTIC using "|" between potentially interactive variables and "@n" tospecify the number of variables that can be involved in an interaction (e.g., "@2" refers to 2-way interactions).Another approach that has been recommended...
