Compared to a logistic model, LPM has advantages in terms of implementation and interpretation that make it an appealing option for researchers conducting impact analysis. WebThis data generating process generates data from a binary choice model. Fitting the model using a logistic regression allows us to recover the structural parameters: logistic_regression <- glm(y ~ ., data = df, family = binomial(link = "logit")) Let’s see a summary of the model fit: summary(logistic_regression)
