Definition of covariance in English:
covariance
noun
1Mathematics
The property of a function of retaining its form when the variables are linearly transformed.- ‘These different models for covariance function with some modifications can be incorporated into our mapping strategy.’
- ‘If this occurs frequently, then MA experiments will be practically useless for studying any properties of mutational covariance.’
- ‘The matrix formulation of the model produces an estimate that can be easily transformed into genetic covariance and correlations.’
- ‘Note that the simulated covariance function was not generated from a polynomial.’
- ‘Contour plots of genetic covariance functions fitted by the character process model.’
2Statistics
The mean value of the product of the deviations of two variates from their respective means.- ‘The direct estimation approach does well in estimating the overall covariance function: on average, the covariances are estimated with an error of 15%.’
- ‘The most common measure of variability is variance and the corresponding measure of correlation between two variables is covariance.’
- ‘Statistically significant covariances among random intercepts, rates of change, and effects of depressed mood and delinquency variety are reported in the text only.’
- ‘Logistic regression was used instead of univariate chi-squares so that covariance among the variables would be taken into account in the analyses.’
- ‘The demographic variances and covariances of the elements are inversely proportional to the total population size.’
