logLik value of the spml spatial panel model
Dear List: In a recent attempt to compare spatial panel models using splm package, I intend to use the logLik value that was produced by the spml() routine. When I ran the model, I realize that the logLik value is not always produced, especially when the spatial.error is set to "b", a NULL value is returned. I know I must have missed something here, but can anyone point out why the logLik value is not returned when the spatial.error value is set to "b" (a spatial panel lag model always return a logLik value). I tried a bit to dig into the codes, but didn't find much that can answer my question. Thank you. Best, Danlin
