Habituation model
Dear all,
I am looking at habituation of dogs trotting on a treadmill.
I record the ground reaction force and I analyze it with several discrete variables (maximum, minimum,...)
For each variable, I get between 40 and 50 data per sample.
I record data at time 1 min, 2 min, and 4 min a day, and I have 4 days of measurement (one day a week).
That means I have 12 samples : Day1_Min1, Day1_Min2,

Habituation model : several sequences in several sessions, should I use getGroups?
Dear all,
I am looking at habituation of dogs trotting on a treadmill.
Each record is made of 40 to 50 data for the same variable (for example
Peak).
I get each record at several minutes (1, 2 and 4) for each session. And
I have 4 sessions of training (one session a week).
The aim is to study the effect of the factor (Minute) on the Peak
variable, and to study the changes of this effect

How to compare areas under ROC curves calculated with ROCR package
Dear all,
I try to compare the performances of several parameters to diagnose
lameness in dogs.
I have several ROC curves from the same dataset.
I plotted the ROC curves and calculated AUC with the ROCR package.
I would like to compare the AUC.
I used the following program I found on R-help archives :

lme: how to compare random effects in two subsets of data
Dear R-gurus,
I have an interpretation problem regarding lme models.
I am currently working on dog locomotion, particularly on some variation
factors.
I try to figure out which limb out of 2 generated more dispersed data.
I record a value called Peak, around 20 times for each limb with a record.
I repeat the records during a single day, and on several days.
I tried to build two models, one
