grouping for lme with nested repeated measurements
...repeated measurements (each sample is measured 6 times) and i repeat this experiment over several Days, so i get the lme grouping term "random=~1|Days/Sample".
2. Now i am measuring with 2 different measuring Apparatus the same Sample each 6 times, to see how big the difference from the appratus is.
Because Apparatus is on the level of repeated measurements i cant write Days/Sample/Apparatus. the lme function offers a list() feature to design the grouping, but i didnt understand this, if it is the solution to the problem.
Maybe somebody had the same Problem?
