MicroFACT is an easy-to-use factor analysis program that can tackle mainframe size problems on your PC quickly!
MicroFACT provides a methodologically defensible and computationally efficient method for factor analysis of both dichotomous and polytomous data sets. Using virtual memory, it can handle analyses of data sets of any size. For dichotomous (i.e., test) data MicroFACT can assist you in verifying the dimensionality of your test (which is one of the most basic assumptions of the application of the item response theory model). Assessing the dimensionality of a test can be accomplished using a factor analytic approach if appropriate computations are employed. The linear factor analysis model as typically implemented in most statistical packages, however, often fails to use the appropriate measures of correlation for such a factor analysis (tetrachoric correlations). MicroFACT makes it easy to analyze the interrelationships among your test items to determine the number of underlying dimensions. MicroFACT is simple to use and provides detailed (but understandable) results. For the factor analysis of other types of data, such as polytomous data (i.e., ordered categorical data such as that found in surveys in the social sciences, political science, education, and behavioral sciences, and clinical measures used in medical, psychological and personality research).
