can a r function fit a variance-mean relationship what is the relationship between variance and mean in quasi likelihood? does r have a function to fit variance variance how to fit a quasi likelihood model in r what model can be fitted between variance and the mean in quasi likelihood which model would allow the use of a quasi likelihood model how can i fit a variance/mean model which model would include a variance-mean model what model is used to fit variance vs mean what type of model is the quasi likelihood model? what is the function that can fit variance which model fits a binomial quasi likelihood model what model of variance is the quasi likelihood model what is the purpose of a r function for variance what model is a quasi likelihood model in r how to model variance variance what model can fit a variance model what is the r function for the variance model r function for calculating variance mean what model can we use for variance
