Re: [R] Coefficients for lagged plm model variables not calculated

Hi Daniel, Thanks for your thoughts on this and taking the time to feed back. There may indeed be some quai-collinearity as you describe in some of the variables, although they are strongly seasonal (they represent commodity prices in rural agricultural systems), but from time period to time perio
