Package: BLPestimatoR 0.3.4

BLPestimatoR: Performs a BLP Demand Estimation

Provides the estimation algorithm to perform the demand estimation described in Berry, Levinsohn and Pakes (1995) <doi:10.2307/2171802> . The routine uses analytic gradients and offers a large number of implemented integration methods and optimization routines.
