class statsmodels.genmod.cov_struct.Exchangeable
[source] -
An exchangeable working dependence structure.
Methods
covariance_matrix
(expval, index)Returns the working covariance or correlation matrix for a given cluster of data. covariance_matrix_solve
(expval, index, ...)Solves matrix equations of the form covmat * soln = rhs
and returns the values ofsoln
, wherecovmat
is the covariance matrix represented by this class.initialize
(model)Called by GEE, used by implementations that need additional setup prior to running fit
.summary
()update
(params)Updates the association parameter values based on the current regression coefficients. Methods
