Powerpoints on various topics are available. You may view one powerpoint free of charge but if you two or more there is a small charge. Please let me know what other topics that you would like to see.
Topics (click on one to see the full list)
Study of the Causes of Change - Two Waves
General Topics
Confirmatory Factor Analysis of Over-time Data (helpful to view before viewing other powerpoints)
Regression toward the Mean
(view webinar)
Two-Wave Intervention Studies
Discussed are models with a single outcome measured at two times or a latent variable with indicators measured at two times with an intervention that causes change.
Introduction (very important to view first)
Change Score Analysis (includes Latent Change Score Analysis or LCA)
Standardized Change Score Analysis
Controling for Baseline (Regression or Analysis of Covariance)
Power
Example
Multiwave Models (three or more time points)
Trait Models
Equality of Means and Variances
Autoregressive Models
Growth Curve Models
TSO and STARTS Models
Example
Cross-causal Effects
Discussed are models in which variables are presumed to have lagged caual effects.
Two-wave Two Variable Model or Cross-lagged Regressions
Cross-lagged Panel Correlation
Time-reversed Analysis
