Multivariate Analysis

The multivariate analysis procedures are used to investigate relationships among variables without designating some as independent and others as dependent.

Below are highlights of the capabilities of the SAS/STAT procedures that perform multivariate analysis:

• exploratory and confirmatory factor analysis
• principal components analysis
• canonical correlation and partial canonical correlation
• canonical redundancy analysis
• simple and multiple correspondence analysis
• analysis of covariance structures
• structural equation modeling and path analysis
  • general COSAN model
  • optimization methods include Levenberg-Marquart algorithm, ridge-stabilized Newton-Raphson, quasi-Newton, and conjugate gradient algorithms
  • estimation methods include maximum likelihood, least squares, generalized least squares, weighted least squares, and diagonally weighted least squares
  • equality and inequality constraints
• multiplicity-adjusted p-values
  • multivariate one-way ANOVA model, discrete or continuous variables
  • linear contrasts to compare proportions or means
  • adjustments include bootstrap and permutation resampling
• two-way and three-way, metric and nonmetric multidimensional scaling models
  • simple Euclidean and weighted Euclidean models
  • ordinal, interval, ratio, or absolute levels of measurement
  • fits distances, squared distances, log distances, or distances raised to any power
