R: Can I analyze non-varying-across-individual alternative-specific attribute variables with mlogit?
问题 I'm new to discrete choice modeling, so my apologies if I am misunderstanding a fundamental aspect of the analysis. I would like to run a discrete choice analysis with an individual-specific variable and what I think are alternative-specific attribute variables. From the mlogit vignette I think the individual-specific variable is a "choice situation specific covariate" (in the new vignette) and the alternative-specific attribute variables are "alternative specific covariates with generic
