class statsmodels.genmod.cov_struct.Independence(cov_nearest_method='clipped')
[source]
An independence working dependence structure.
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 () | Returns a text summary of the current estimate of the dependence structure. |
update (params) | Updates the association parameter values based on the current regression coefficients. |
