Methods for corStruct derivatives #4

Closed jepusto closed 4 years ago

jepusto commented 4 years ago

Write S3 methods for dV_dcorStruct(), which calculate derivatives of marginal variance covariance matrix with respect to level-1 correlation parameters.

jepusto commented 4 years ago

Should be able to handle corAR1, corCAR1, corCompSymm, and corSymm, at least.

See lme:::corMatrix.corAR1() and related for guidance on constructing derivatives.
