Abstract: | Meredith's method of extracting a factorially invariant solution is adapted to longitudinal settings. An explorational estimation
procedure is presented which attempts to identify the longitudinal factor components of an across occasion variance-covariance
matrix. This is effected by transforming an initial factor pattern matrix to stationarity. The estimation is performed in
two parts, the first employing a stepwise algorithm to ascertain the dimensionality and existence of the longitudinal components
and the second being the direct estimation of the existing factor pattern. |
