Definition of covariant in English: covariantnoun kəʊˈvɛːrɪəntˌkoʊˈvɛriənt Mathematics A function of the coefficients and variables of a given function which is invariant under a linear transformation except for a factor equal to a power of the determinant of the transformation. Example sentencesExamples - This was significant even after adjustments for covariants.
- This was dealt with by using the SES score as a covariant in the analysis.
- Baseline covariants were included in models that were judged a priori to be clinically sound.
- One-way analysis of covariance, with pretest scores as covariants, were used when tests for homogeneity of variance dictated that ANCOVA was warranted.
- Residual depression scores and negative affectivity scores also were linked to cardiac-related mortality after adjusting for each other and for cardiac covariants.
adjective kəʊˈvɛːrɪəntˌkoʊˈvɛriənt Mathematics 1Changing in such a way that mathematical interrelations with another simultaneously changing quantity or set of quantities remain unchanged. Example sentencesExamples - Size change is so covariant among morphological traits in general that separate body parts are often good estimators of change in other parts.
- Salmon, in his famous text, gave an equation in covariant form.
- In 1887 he published a famous paper in which he developed the calculus of tensors, following on the work of Christoffel, including covariant differentiation.
- Moreover, for the minor factorial axis, the covariant part of characters becomes less intuitive and noise becomes more important.
- The special theory of relativity is notorious for positing laws that turn what we thought were invariant quantities, e.g., length, duration, and mass, into covariant quantities.
- 1.1 Relating to or having the properties of a covariant.
Example sentencesExamples - Thus each axis can be seen as a composite morphological character combining the covariant part of the initial morphometric parameters.
- Salmon, in his famous text, gave an equation in covariant form.
- However, such covariant mutation can also occur within closely related groups.
- Moreover, for the minor factorial axis, the covariant part of characters becomes less intuitive and noise becomes more important.
- In the theory of relativity, there are both covariant and invariant laws.
