Interpretation PROBIT model

x1, x2 and x3 are more likely to have a contract with middlemen, and x4, x5 and x6 are less likely to have a contract. Marginal effect (ME): x1, x2 and x3 are N% more likely to have a contract with middlemen. The predicted probabilities are limited between 0 and 1. Probit are estimated using the ML method. an increase in x increases/decreases the likelihood that y=1 an increase in x makes the outcome of 1 more likely. We interpret the sign of the coefficient but not the magnitude. The magnitude can’t be interpreted using the coefficient because different model […]

Source: http://www.ats.ucla.edu/stat/mult_pkg/whatstat/nominal_ordinal_interval.htm What is the difference between categorical, ordinal and interval variables? In talking about variables, sometimes you hear variables being described as categorical (or sometimes nominal), or ordinal, or interval.  Below we will define these terms and explain why they are important. Categorical A categorical variable (sometimes called a nominal variable) is one that has two or more categories, but there is no intrinsic ordering to the categories.  For example, gender is a categorical variable having two categories (male and female) and there is no intrinsic ordering to the categories.  Hair color is also a categorical variable having a number of […]
