statsmodels.base.model.Model¶

class
statsmodels.base.model.
Model
(endog, exog=None, **kwargs)[source]¶ A (predictive) statistical model. Intended to be subclassed not used.
 Parameters
 endogarraylike
1d endogenous response variable. The dependent variable.
 exogarraylike
A nobs x k array where nobs is the number of observations and k is the number of regressors. An intercept is not included by default and should be added by the user. See
statsmodels.tools.add_constant
. missingstr
Available options are ‘none’, ‘drop’, and ‘raise’. If ‘none’, no nan checking is done. If ‘drop’, any observations with nans are dropped. If ‘raise’, an error is raised. Default is ‘none.’
 hasconstNone or bool
Indicates whether the RHS includes a usersupplied constant. If True, a constant is not checked for and k_constant is set to 1 and all result statistics are calculated as if a constant is present. If False, a constant is not checked for and k_constant is set to 0.
Notes
endog and exog are references to any data provided. So if the data is already stored in numpy arrays and it is changed then endog and exog will change as well.

Methods
fit
()Fit a model to data.
from_formula
(formula, data[, subset, drop_cols])Create a Model from a formula and dataframe.
predict
(params[, exog])After a model has been fit predict returns the fitted values.
