A very simple example: import numpy as np import statsmodels.formula.api as sm from sklearn.linear_model import LogisticRegression np.random.seed(123) n = 100 y = np.random.random_integers(0, 1, n) x = np.random.random((n, 2)) # … You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. family (family class instance) A pointer to the distribution family of the model. A 1-d endogenous response variable. The following are 14 code examples for showing how to use statsmodels.api.Logit().These examples are extracted from open source projects. exog array_like. Here, you'll model how the length of relationship with a customer affects churn. To this issue: The easiest would be to raise immediately an exception if endog is 2d in disctete_model.BinaryModel.__init__.. For most users it would work using endog[:, -1] or 1 - endog[:,0] for the binary models if endog is 2-d. summary () Optimization terminated successfully. The dependent variable. fit result. df_model (float) p - 1, where p is the number of regressors including the intercept. You then use .fit() to fit the model to the data.. It also supports to write the regression function similar to R formula.. 1. regression with R-style formula. Current function value: 0.365688 Iterations 7 df_resid (float) The number of observation n minus the number of regressors p.: endog (array) See Parameters. statsmodels.discrete.discrete_model.Logit¶ class statsmodels.discrete.discrete_model.Logit (endog, exog, check_rank = True, ** kwargs) [source] ¶ Logit Model. logit (""" loan_denied ~ loan_amount + income """, data = merged) result = model. %matplotlib inline from __future__ import print_function import numpy as np import pandas as pd from scipy import stats import matplotlib.pyplot as plt import statsmodels.api as sm from statsmodels.formula.api import logit, probit, poisson, ols import statsmodels.formula.api as smf model = smf. Logistic regression requires another function from statsmodels.formula.api: logit().It takes the same arguments as ols(): a formula and data argument. I'm pretty sure it's a feature, not a bug, but I would like to know if there is a way to make sklearn and statsmodels match in their logit estimates. In statsmodels it supports the basic regression models like linear regression and logistic regression.. Parameters endog array_like. Despite its name, linear regression can be used to fit non-linear functions. $\begingroup$ @desertnaut you're right statsmodels doesn't include the intercept by default. exog (array) See Parameters. if the independent variables x are numeric data, then you can write in the formula directly. \[\Lambda\left(x^{\prime}\beta\right)=\text{Prob}\left(Y=1|x\right)=\frac{e^{x^{\prime}\beta}}{1+e^{x^{\prime}\beta}}\]
