In dictionaries:
Covariance matrix
Measures variability between multiple variables.
General covariance
In theoretical physics, general covariance, also known as diffeomorphism covariance or general invariance, consists of the invariance of the form of physical laws under arbitrary differentiable coordinate transformations.
covariance method
Statistical measure of variable association.
Eddy covariance
The eddy covariance (also known as eddy correlation and eddy flux) is a key atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers.
Lorentz covariance
In relativistic physics, Lorentz symmetry or Lorentz invariance, named after the Dutch physicist Hendrik Lorentz, is an equivalence of observation or observational symmetry due to special relativity implying that the laws of physics stay the same for all observers that are moving with respect to one another within an inertial frame.
serial covariance
Correlation between ordered data points.
manifest covariance
In general relativity, a manifestly covariant equation is one in which all expressions are tensors.
Analysis of covariance
Statistical control for background variables.
