Hi All, I will be glad is someone can kindly help me out with this. I have a split plot experiment based on randomized complete block design (RCBD) with two factors (crop rotations and tillage practices) and four replications. I analyzed my results using PROC MIXED (but with no interactions, that was the way I wanted it). My code for multi year analysis proc mixed data= Data; class Year Rep T_System; model &var = T_System; random Rep(year)year year*T_System/solution; repeated year/subject=rep*T_System type=ar(1) RCORR; Lsmeans T_System/diff=all; I wrote my statistical text as: "The results from each year were analyzed separately with treatments (tillage and rotations) and replication treated as fixed effect and random effect, respectively. Combined analysis was then carried out using repeated measures and year was assumed as a random effect. Differences among treatments were tested using the Tukey HSD test". But someone commented that My text appeared as if tillage and rotation were considered as independent factors, and if that had been the case I should have analyzed them as such, with interactions, etc. Please how better do I construct my statistical text Thanks -Ola
