__init__ ([cov_nearest_method]) |
|
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 of soln, where covmat 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. |
