Dear list

 

I’m modeling fish activity data with a gaussian distribution for scores
obtained from Principal Component Analysis. My explanatory variables are
group size, fish length, temperature and year. Because year has only two
levels I know I can’t use it as a random effect. However, do you think that
considering year a fixed effect will affect the relationship between the
other explanatory variables and the response? If the answer is yes, do you
know of other statistical technique I could use?

Thank you

 

All the best 

Joana
