Yes, fair enough. I wasn't sure it was fitting the mode at all, but here is an example of what I see > model <- betareg(ACT ~ ST+DOY, data = actDL_F) Warning messages: 1: In sqrt(diag(fisherinv)) : NaNs produced 2: In sqrt(diag(fisherinv)) : NaNs produced 3: In sqrt(W) : NaNs produced 4: In sqrt(

Hi I'm trying to fit a model in betareg and I'm getting errors, but have no idea what they mean or how to solve them. Does anyone have experience with this? > model <- betareg(ACT ~ ST*SoilT, data = actDL_F) Warning messages: 1: In sqrt(W) : NaNs produced 2: In sqrt(W) : NaNs produced 3: In sqrt
