In statistics, a linear probability model (LPM) is a special case of a binary regression model. Here the dependent variable for each observation takes values which are either 0 or 1. The probability of observing a 0 or 1 in any one case is treated as depending on one or more explanatory variables. For the "linear … Visa mer More formally, the LPM can arise from a latent-variable formulation (usually to be found in the econometrics literature, ), as follows: assume the following regression model with a latent (unobservable) dependent variable: Visa mer • Linear approximation Visa mer • Aldrich, John H.; Nelson, Forrest D.
