Hi,   I have the code for estimating mean cost and estimating the incremental effectivness Ratio using censored data from the SAS book "Analysis of Observational Health Care Data".   However, the code was written using the SAS?IML software. Unfortunately, i can not post the code here but anyone familiar with the code or if anyone knows any other SAS program to do the same please let me know.   Can anyone help/provide what modifications can i do to use it with base SAS?   Any help is greatly appreciated. Thank you!   Thank you! ... View more
