Dear list,
I am trying to fit a regression model using a dataset containing dependent
variable as a percentage (arcsine transformed) and a categorical
independent variable controlled for phylogeny using PGLS. Following the
post below, I found the normality of the residuals to be non-normal as the
data is right skewed (zero-inflated). Is there any way to overcome this

Thanks in advance,
Gopal Murali
