We applied confirmatory factor analyses (CFA) by using the maximum likelihood procedure with robust standard errors using Mplus (version 7.11; cf. Muthén and Muthén 1998 2012).
Model estimation was performed with Mplus 5.2 using the maximum likelihood procedure with robust standard errors (MLR) in order to account for non-normality in the data.
We additionally tested the selection hypothesis over 5-year intervals (i.e., from phase 3 to phase 5 and from phase 5 to phase 7) using multilevel longitudinal modeling (xtmixed and xtlogit procedures in Stata) with robust estimation to take into account the fact that repeated measurements on the same participant are correlated.
The procedure is technically simple with robust results because the amplification product is always obtained (Drenkard et al. 1997).
The procedure effectively distinguishes substances with robust concentration response profiles (ACTIVE*[±1] and ACTIVE*[±2]) and compounds with nonrobust concentration response profiles (INCONCLUSIVE*[±3]).
Managers can find it difficult to discuss issues like depression, so it's important for companies to help them with robust policies, procedures and training.
Access to large visual field and differentiation of retinotopic areas with robust mapping procedures and automated analysis are beneficial in basic research and could accelerate development of clinical applications.
This study demonstrates that a trial of this type is feasible in primary care and can be successfully completed with robust trial procedures and high levels of follow up.
In order to cope with (unstructured) parametric uncertainties we insist on well-known high-gain design principles which, however, are integrated with robust zero-assignment procedures to handle possible unstable zero dynamics.
Although auto-correlation will lead to biased estimates of the sampling variance of the effect size, meta-analysis of response ratios can be conducted with robust variance estimation procedures that remain valid even when sampling variance estimates are biased.
