Hello SAS Community! I am having a bit of trouble figuring out the best code to use for my experiment. The more I work to fix my syntax, the more confused that I get. Background: This is set up as a split plot design with repeated measures. The main plot is two different animal diets (n=5 per treatment). The subplot consists of each animal being treated with 7 different hormones and having one control. Response variable were measured at 4 different time periods (24, 48, 72, and 96 hours). The data is non-normally distributed and a log transformation must be done. Homogeneity is good. Below is my code with example data (not complete or accurate responses). I also need to correctly get a means separation test into the code. Note: red and green refer to the two different diets. data CLP4; input diet $ hormone $ P24 P48 P72 P96; logP24=log(P24); logP48=log(P48); logP72=log(P72); logP96=log(P96); datalines; Green Control 861.32 162.11 119.865 28.276 Green Control 1135.02 238.79 155.245 29.156 Red Control 735.28 236.76 162.445 55.276 Red Control 605.66 159.37 85.745 23.012 Red hCGhigh 1327.96 313.22 110.92 23.348 Red hCGhigh 1270.6 338.74 179.25 65.848 Green hCGhigh 511.02 179.81 132.59 65.81 Green hCGhigh 583.68 186.54 147.97 65.214 Red hCGlow 1593.04 178.93 129.305 24.524 Red hCGlow 1217.32 188.14 116.29 34.58 Green hCGlow 1124.98 215.46 172.355 53.776 Green hCGlow 1134.72 307.38 182.755 53.194 Green Lhhigh 1066.66 174.89 98.87 21.806 Green Lhhigh 971.68 157.94 96.47 29.132 Red Lhhigh 1269.44 203.6 129.8 28.152 Red Lhhigh 1116.28 205.19 117.04 36.484 Green Lhlow 1579.42 157.65 87.445 16.3618 Green Lhlow 832.18 141.38 . 21.344 Red Lhlow 1164.04 236.01 117.305 43.928 Red Lhlow 1229.82 245.31 120.22 21.252 Green Lhlow 880.78 166.95 166.25 53.41 Green Lhlow 824.12 192.95 208.71 75.614 Green PGEhigh 892 168.11 127.925 44.886 Green PGEhigh 909.5 240.74 133.37 28.458 Red PGEhigh 1025.72 311.68 206.7 56.778 Red PGEhigh 1163.88 313.18 174.51 44.816 Green PGElow 1170.58 232.94 160.64 39.612 Green PGElow 1167.52 277.79 150.705 38.01 Red PGElow 658.18 198.81 118.925 30.568 Red PGElow 776.2 221.04 145.615 46.994 Red PGEmed 1095.34 277.01 229.63 70.582 Red PGEmed 896.92 309.11 175.595 64.732 Green PGEmed 1051.36 288.48 212.295 63.306 Green PGEmed 1368.44 267.82 244.565 93.674 ; proc mixed data CLP4; class diet hormone; model logP24- -logP96= diet hormone diet*hormone/ ddfm=KR; repeated time 4 (24 48 72 96) polynomial/summary printe; lsmeans diet hormone diet*hormone/pdiff lines; run;
