pipefitter.estimator.LogisticRegression

class pipefitter.estimator.LogisticRegression(intercept=True, max_effects=0, selection='none', sig_level=0.05, criterion=None, target=None, nominals=None, inputs=None)

Bases: pipefitter.base.BaseEstimator

Logistic Regression

Parameters:

intercept : bool, optional

Include the intercept term in the model?

max_effects : int, optional

Specifies the maximum number of effects in any model to consider during the selection process

selection : string, optional

Specifies the selection method. Valid values are ‘none’, ‘backward’, ‘forward’, and ‘stepwise’.

sig_level : float, optional

Specifies the significance level

criterion : string, optional

Specifies selection criterion. Valid values are ‘sl’, ‘aic’, ‘aicc’, and ‘sbc’.

target : string, optional

The target variable

nominals : string or list of strings, optional

The nominal variables

inputs : string or list of strings, optional

The input variables

Returns:

LogisticRegression

Examples

>>> log = LogisticRegression(target='Origin',
...                          inputs=['MPG_City', 'MPG_Highway', 'Length',
...                                  'Weight', 'Type', 'Cylinders'],
...                          nominals = ['Type', 'Cylinders', 'Origin'])
