Discrete-time event history analysis is a powerful parametric regression technique for modeling whether and when events occur in abstracted (i.e. discrete) units of time. I have implemented methods introduced to me through the event history analysis curriculum of Judith Singer and John Willett within the context of educational and sociological research.dthaz is currently available for Stata on the web here, and from within Stata by typing:

Loop analysis is a body of methods for understanding the nature of system behavior in systems of causal feedback. Originally devised by Richard Levins as a means of creating testable hypotheses about the behavior of dynamic systems in population biology, loop analysis has a very general application in sciences concerned with modeling causal feedback.Loop Analyst is currently available for R on the web here, and from CRAN. A stand-alone version with GUI is in beta release, see the Loop Analyst page for details and download.
Parallel analysis is a general method to reliably assess the underlying dimensionality of multicolinear data. Originally devised by John L. Horn, the method has been favorably compared to other dimensional analysis methods and modified slightly over the years.paran is currently available as an ado for Stata on the web here, and from within Stata by typing:
net describe paran, from(http://www.doyenne.com/stata)paran is also available as an R-project package on the web from CRAN.
