corClasses: Correlation Structure Classes
Description
Standard classes of correlation structures (corStruct
)
available in the nlme
library.Value
- Available standard classes:
- corAR1autoregressive process of order 1.
- corARMAautoregressive moving average process, with arbitrary
orders for the autoregressive and moving average components.
- corCAR1continuous autoregressive process (AR(1) process for a
continuous time covariate).
- corCompSymmcompound symmetry structure corresponding to a
constant correlation.
- corExpexponential spatial correlation.
- corGausGaussian spatial correlation.
- corLinlinear spatial correlation.
- corRatioRational quadratics spatial correlation.
- corSpherspherical spatial correlation.
- corSymmgeneral correlation matrix, with no additional
structure.
