We postulate that shocks that are common to many sectors, such as changes in interest rates, the exchange rate and aggregate demand will tend to raise the sector co-variance
and raise GDP volatility.
For the most part, the comparison of an intervention and matched comparison groups can be done with a t-test of the means or an analysis of co-variance
on post-EAP averages controlling for pre-EAP scores.
It builds a bridge between, on the one hand, a recently renewed interest in conceptual analysis which extends our knowledge and, on the other hand, externalist semantics according to which concepts have objective content by means of their proper co-variance
with real structures to which they thus refer.
Direct and maternal co-variance
components and heritability estimates for body weight at different ages and fleece traits in Afrino Sheep.
Multiple analyses of co-variance
(MANCOVAs), controlling for ethnicity, age group and gender, were used to investigate the effects of chronic disease status (group 1: no chronic disease; group 2: hypertension alone; group 3: hypertension plus one or more other chronic diseases; and group 4: other chronic diseases without hypertension) on health and well-being (Fig.
The researchers used an analysis of co-variance
model, adjusting for baseline heavy drinking days, to examine factors associated with change in the frequency of heavy drinking.
