Abstract
An implementation of the MAP procedura for determining the number of factors. How many factors to retain is a common problem in Factor Analysis that hasn't been solved yet. The eigenvalues greater than 1 rule is commonly used since its a built-in option in most statistical packages. Nevertheless, there are other more effective rules available, like MAP, that can also be easily worked out. Here we present a program towards computing the MAP procedure, to be executed inside one of the most widely used packages.
