## Parallel analysis

Parallel analysis (Horn, 1965) is a sample matrix based adaptation of the K1 method, in which factors with eigenvalues greater than 1 are considered significant, on the basis of the correlation matrix of the population.mands for parallel analysis appear in AppendixC, and SAS commands appear in Appendix D. The user simply speci-fies the number of cases, variables, data sets, and the de-sired percentile for the analysis at the start of the program. Unlike the MAP program, the commands in Appendices C and D do not read in the user's correlation matrix (althoughFigure 3. Parallel line analysis of two predictor fluorescence polarization curves. With parallelism analysis, curve parameters for both individual curves are provided, as are parameters for the constrained curves. While the constrained curves have the same values for all parameters, the experimental curve has an extra

In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables.EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. It is commonly used by researchers when developing a scale ...To carry out parallel analysis, generate N observations from a normal distribution for p variables (N and p for the simulated data match those for the observed data). Then compute the reduced correlation matrix among simulated MVs and its eigenvalues, repeat this process approximately 100 times, and average the eigenvalues for each simulated MV.
