ModA <- lm(Temperature ~ Section*sin(2*pi*t)+Seccion*cos(2*pi*t),data=MyData)
ModB <- lm(Temperature ~ Section+sin(2*pi*t)+cos(2*pi*t),data=MyData)
I have to specify the statistical methods in my paper so, is it correct to say that these are ANCOVA models or they are only linear models with parallel slopes and interactions?
