Hi everyone! My experiment is related to hormonal treatment. There were 5 treatments at five doses of hormone (T1 to T5) and one control (12 replicates per treatment, 1 fish per replicate). The anal fin rays 3 and 4 of the fish were measured at 0, 7, 14, 21, 28, 35, 42, 50 days during treatment period. The width ratio of anal fin rays 3 and 4 were measure. I’m learning to use mixed effects model to analyze my data but I’m not quite sure that the model I used was right or not. Could you please help me to have a look at my data and the output and give me advice on what model should I use. Thank you very much in advance!
