Correlations among variables are provided in Table I based on an initial confirmatory factor analysis of a 5 - factor,
correlated measurement model (χ2 = 550.35, df = 125, p <.01, RMSEA = 0.05, and CFI = 0.93).

The IPCC claims the
models» global (wide) mean annual temperatures is highly

Modification indices for covariances among
measurement errors suggested that allowing the items «run one or more red lights» and «speed through a yellow light» to
correlate would substantially improve the

measurements taken at successive points in time are equally
correlated or that they have an unstructured pattern of correlations) to be
modeled.
Further,
measurement invariance across parental roles was tested applying the modified version of the
