Methods
fit
([smoothing_level, optimized, …])Fit the model
from_formula
(formula, data[, subset, drop_cols])Create a Model from a formula and dataframe.
hessian
(params)The Hessian matrix of the model.
information
(params)Fisher information matrix of model.
Compute initial values used in the exponential smoothing recursions
Initialize (possibly re-initialize) a Model instance.
loglike
(params)Log-likelihood of model.
predict
(params[, start, end])Returns in-sample and out-of-sample prediction.
score
(params)Score vector of model.
Properties
Names of endogenous variables.
