Web1. One Factor Confirmatory Factor Analysis. The most fundamental model in CFA is the one factor model, which will assume that the covariance (or correlation) among items is due to a single common factor. Much like exploratory common factor analysis, we will assume that total variance can be partitioned into common and unique variance. Webthe number of variables makes it easier to run the cluster analysis. Also, the factor analysis minimizes multicollinearity effects. The next analysis is the cluster analysis, which identifies the grouping. Lastly, a discriminant analysis checks the goodness of fit of the model that the cluster analysis found and profiles the clusters.
