The Stability of Post Hoc Model Modifications in Covariance Structure Models.

Download full text

Hutchinson, Susan R. – 1994

The work of R. MacCallum et al. (1992) was extended by examining chance modifications through a Monte Carlo simulation. The stability of post hoc model modifications was examined under varying sample size, model complexity, and severity of misspecification using 2- and 4-factor oblique confirmatory factor analysis (CFA) models with four and eight…

Are Multilevel Techniques Necessary? An Attempt at Demystification.

Download full text

Kreft, Ita G. G.; Yoon, Bokhee – 1994

The merits of the multilevel model for educational research and its uses for school effectiveness research are considered. The main goal of the paper is to establish what intelligent applications of multilevel models can do, helping researchers decide what they must do to make a rational choice between models. Multilevel models are random line…
