For example, the sharp fall in GDP volatility in the mid 1990s was primarily the result of a temporary fall in the co-variance
of growth between the sectors.
Genetic variances and co-variances
reflect how selection can be applied in the farms.
The graphical representation of variance (Vr) and co-variance
(Wr) proposed additive gene action with partial dominanceaction.
Do this for all demes, and examine the co-variance
among the pairs of measures.
Both analyses were done using the free R software's sem package (Fox, Nie & Byrnes, 2013), taking as entry data the matrix of variances and co-variances
of the items involved.
Genotypic and environmental variance and co-variances
in an upland cotton cross of interspecific origin.
A manual for use of MTDFREML: a set of programs to obtain estimates of variances and co-variances
The analysis of the measurement models let to the elimination of some indicators (totally, three indicators that presented saturations inferiors to 50) and the introduction of co-variances
between errors of measures (totally, three co-variances
between errors of measures in the mediator model of measurement).
Topics include: bivariate statistical tests, data evaluation, regression analyses (simple, multiple, and logistic), analysis of variances and co-variances
(two-way, multivariate, and repeated measures), and canonical correlation analysis.
Even aside from problems connected with unscrupulous promoters, high rate-of-return variances and co-variances
within and between the peripheral countries, together with large and infrequent (and hence underestimated) shocks, could easily have disturbed well-laid plans.
