converting a BMDP 8V mixed model to R / nlme
...rson. fixed = retest,ground,direct,flicker. model = 'P,R,G,D,F'. /end. /finish. BMDP 8V calculates the anova and reports F-values for tests of all fixed effect interactions against the error from the interaction with person variables. Also estimates of variance components. (BMDP is used on uVAX3100 , 24MB, VMS system, CPU time 20 s for this problem). I tried to translate the setup to R. The nearest equivalent I got was: latm <- read.table("latm.dat" ) latm.aov <- aov( llat ~ person + retest * direct * flicker * ground + Error ( person : ( retest * direct * flicker * ground )...
