Hi all, I am trying to use R package flexmix for data clustering which I find extremely useful. I would like to know how many clusters could be there in the data and the assignment of trials to these clusters. The data are hand kinematics data- 16 variables at 10 discrete time points for 17 subjects. I am trying to use the FLXMCmvnorm driver for as the data features are correlated multinomial features (formula - data~time|subject). However, using the driver, I found out that only the left hand side in the formula is used. This would remove the time dependence that I am trying to model. Currently, I am stuck at this point. I would really appreciate if any one could provide me any help on how in the formula I can include the time dependence as well. I would really appreciate help regarding this and would go a long way in solving my problem. Please let me know if more information about the data is needed. Thanks, Best regards, Atesh [[alternative HTML version deleted]]
