Simstat v2.5 Statistical Analysis and Simulation Software

EASY FACTOR ANALYSIS v4.0

 ANNOUNCEMENT: January 26, 2004 - Easy Factor Analysis is now part of Simstat 2.5. It is no longer sold separately.

EASY FACTOR ANALYSIS v4.0 is an add-on module written by Dr. Darren Fuerst that allows even computer neophytes to perform two common types of factor analysis: principal components analysis and image covariance factor analysis. The program provides several features such as stopping criteria based on the total number of factors or minimum eigenvalue, a varimax rotation, the printing of correlation matrix, eigenvalue table, factor patterns, weights and scores for both rotated and unrotated solutions, etc. It is also possible to automate factor analysis using SIMSTAT's command language and use the RECORD SCRIPT function to easily generate proper commands corresponding to actions undertaken with the interactive user's interface.

FEATURES

• Image covariance or principal components and principal axis analysis on up to 2000 variables.
• QType factor analysis
• Number of factors extracted can be set manually or adjusted to a minimum eigenvalue criteria
• Scree plot of eigenvalues.
• Optional varimax orthogonal rotation of factor loadings.
• Optional printing of descriptive statistics and correlation matrix for all the variables in the data set.
• Printing of unrotated and/or rotated factor solutions.
• Can compute factor scoring weights for both the rotated and unrotated solutions.
• Factor scores can be displayed on screen or saved on disk
