WebApr 8, 2024 · As a result, such a process pertains to this specific definition of first-order stationarity, but not to N-th order stationarity for N=1. Cyclostationarity. A stochastic process is cyclostationary if the joint distribution of any set of samples is invariant over a time shift of mP, where m∈ℤ and P∈ℕ is the period of the process:

WebWe illustrate testing measurement invariance in a second-order factor model using a quality of life dataset (n = 924). Measurement invariance was tested across 2 groups at a set of hierarchically structured levels: (a) configural invariance, (b) first-order factor loadings, (c) second-order factor loadings, (d) intercepts of measured variables, (e) intercepts of first …
