WebbKeywords and phrases: Bayesian approach, probit regression, nonin-formative prior, Monte Carlo sampling. 1. Introduction The analysis of binary response data is important in statistics and related areas including econometrics and biometrics. The classical maximum likeli-hood method and inferences based on the associated asymptotic theory is Suppose data set contains n independent statistical units corresponding to the model above. For the single observation, conditional on the vector of inputs of that observation, we have: where is a vector of inputs, and is a vector of coefficients. The likelihood of a single observation is then In fact, if , then , and if , then .
