Tabachnick and Fidell (2007) also offer sample size suggestions for achieving sufficient power in multivariate studies.
Comprehensive multivariate studies are needed before any conclusion can be drawn about the relationship between outdoor lighting and crime.
She found, however, that the instruments were used in isolation--rarely, if ever, were two or more used in the same study to establish criterion validity--and recommends large, interdisciplinary, multivariate studies. The purpose would be to expand, explicate, and validate both current and emerging theories and instrumentation related to caring.

In this piece, I locus on one aspect of Jensen's research into the nature of human intelligence--his work on reaction times (RTs) and speed of information-processing--and illustrate how his pioneering work in this area has evolved from a few early studies with the Hick apparatus, through more extensive multivariate studies, to univariate and multivariate behavioral genetic investigations, and most recently, to studies of the biological basis of intelligence.
One is tempted to attribute the upward trends in the early 1970s to ESP, but multivariate studies that adjust for confounding influences generally report no significant changes in this utilization measure (Ginsburg, 1976; Coelen, Mennemeyer, and Fidder, 1986).
In a review of the empirical work, Steinwald and Sloan (1981) found that descriptive studies of the effects of ESP and other regulatory programs showed larger reductions in hospital costs than did multivariate studies adjusting for confounding influences such as CON, section 1122 programs, utilization review activities, and other factors.
Multivariate studies showed smaller changes in profit margins than descriptive studies, because multivariate studies incorporated efforts to adjust for factors other than ESP that influenced hospital behavior.
Multivariate studies showed a relatively strong impact of ESP on wages and employment.
With the exception of admission patterns, multivariate studies generally found smaller changes in utilization than noted above in our trend analyses (Figures 7-9).
