The data is at the store/week level for 3 brands and 3 package sizes. csv. I present a new command, blp, for this estimator. BLP reports that with this new coefficient on price, only 22 of the 2217 models have an inelastic elasticity of demand. csv OTC Headache. The reference to the Stata manual is :Vincent, D. The models covered include the random coefficient logit model of Berry, Levinsohn and Pakes (1995) (BLP), nested logit models (with one, two or three nesting level), as well as the simple logit model. Abstract. We outline details of the model, the contraction mapping, and both classical and Bayesian approaches to estimation.
