To demonstrate implementation of the EM algorithm for a Probit regression model using Rcpp-provided functionality we consider a series of steps. These are: Attempt 1: Main Structure Attempt 2: EM with Mistaken Augmentation Attempt 3: EM with Correct Augmentation Attempt 4: EM with Correct Augmenta...
The PROBIT procedure fits a common slopes cumulative model, which is a parallel-lines regression model based on the cumulative probabilities of the response categories rather than on their individual probabilities. The cumulative model has the form Pr.Y Ä 1 j x/ D F .x0ˇ/ Pr.Y Ä i...

Farmers in the East Gojjam Zone of northwest Ethiopia have four market outlet options for selling garlic: consumers, retailers, wholesalers, and assemblers. The econometric model took these four outlets into account. Table5shows the outcome of the multivariate probit regression model (MVP). ...
