Hi All,   I have data of an experiment on which I started working on for my own learning. The objective of the experiment is to investigate the effect of row spacing on grain moisture content that was measured in a 2x2 factorial (four replications) where each treatment (variety and row spacing) was measured weekly for grain moisture content till harvest.   I think the data/exp fits for repeated measure analysis? Following is the model: options linesize=78; Data moisture; Input variety$ row_spac Block Week_1 to Week_10; datalines; Variety Row_Spac Block Week_1 Week_2 Week_3 Week_4 Week_5 Week_6 Week_7 Week_8 Week_9 Week_10 Variety_A 30 1 68.33 65.08 58.42 54.42 51.25 44.92 40.08 31.50 26.25 17.56 Variety_A 60 1 67.58 65.33 61.08 58.58 55.83 52.50 46.75 39.42 27.17 18.10 Variety_A 22 1 69.08 65.50 59.33 55.08 51.17 45.92 38.67 33.33 29.00 17.00 Variety_A 15 1 71.50 67.33 64.25 60.50 52.42 42.75 39.92 35.17 29.58 16.89 Variety_B 30 1 67.00 62.67 58.67 54.83 53.17 46.83 39.58 31.67 26.83 19.30 Variety_B 60 1 64.67 61.17 58.58 54.67 55.00 50.92 43.00 34.92 32.42 19.20 Variety_B 22 1 67.42 62.17 59.67 55.25 51.17 44.50 38.58 34.25 27.83 17.60 Variety_B 15 1 66.83 67.25 63.00 62.67 51.08 47.25 38.25 31.67 29.50 18.90 Variety_A 15 2                     Variety_A 22 2                     proc glm data=moisture; class variety row_spac; model Week_1 to Week_10 = row_spac|variety; repeated time 10; lsmeans row_spac variety; run;   Please, suggest/comment advise on the sas model. I have tried running this model with some modifications but I do not get correct df (320-1). I must be making a mistake that I do not realize.Thank you.   ... View more
