I am running statistics on survival of planted tree seedlings using SAS 9.3. Each seedling received a 1 for alive or a 0 for dead. Because I'm using binary data, I don't have a normal distribution. I want to use proc glimmix to transform my distribution.   This is what I entered in the editor: data rcb; infile 'F:\RC_2016\Field_Study_Data.csv' DLM=',' DSD MISSOVER firstobs=2; input site $ mulch herb  species $ seedling  Alive n; run; proc print data=rcb; run; proc glimmix data=rcb ; class site species mulch herb seedling ; model Alive (event='1') = mulch herb species mulch*herb mulch*species herb*species mulch*herb*species/s dist=binary link=logit; random  site site*mulch site*herb site*species site*mulch*herb site*mulch*species site*herb*species /s; run;   When I use univariate to look at normality and my distribution, it has not changed. What am I missing?   Thanks for your time, Luke. ... View more
