For my final project I am analyzing a data set of my choice and using the statistical methods I learned in the course. However the project I chose requires me to do some research on statistical methods for time-dependent variables as we did not learn them in the course (the professor approved my project but said I needed to do this). I found a data set with the size of insect eggs for 6700 insect species that was collected over a couple hundred years. I am comparing the size of these egges between the 8 genuses over time (bigger smaller no change). I have done a little research and found methods like the Cox Proportional Hazard Model but not I am not sure if I should use this. Are there any other methods? Maybe a two-way ANOVA? (which I did learn in this course). Any input would be greatly appreciated.
