Hi I can able to analyse ordered category multinomial data for the ungrouped data using R, but I have a problem to apply the method for the group data. Alternative is to rearrange the data into ungroup form. But I would like to analyse the data in group format. Advice on this is highly appreciated. The form of the data set is Site Treatment UD PD FD 1 Control 12 50 150 Treated in Early Stage 76 30 15 Treated in Intermediate Stage 36 40 25 Treated in Mature Stage 20 30 60 2 ....... .... ... ... The response variable (seed development stage is counted in the seed pod) is ordered category of three levels such as Undeveloped (UD), Partially Developed (PD), and Fully Developed (FD).
