Ik denk achteraf dat het juist goed is om geen vastliggende contactlegging methodiek te hebben, want iedere cliënt is immers verschillend. Dit is ook de reden dat ik mijn onderzoeksvraag in de loop van de tijd veranderd heb. In eerste instantie wilde ik onderzoeken op welke manier er contact gelegd wordt …

The assumptions of the model for factor analysis do not exclude a class of indeterminate covariances between factors and error variables (Grayson, 2003). The construction of all factors of the model for factor analysis is generalized to incorporate indeterminate factor-error covariances. A necessary …

If the ratio m/p tends to zero, where m is the number of factors m and p the number of observable variables, then the inverse diagonal element of the inverted observable covariance matrix (σ pjj) -1 tends to the corresponding unique variance ψ jj for almost all of these (Guttman, 1956). If the smallest …

Sufficient conditions for mean square convergence of factor predictors in common factor analysis are given by Guttman, by Williams, and by Schneeweiss and Mathes. These conditions do not hold for confirmatory factor analysis or when an error variance equals zero (Heywood cases). Two sufficient conditions …
