Well, there is summary_col in statsmodels; it doesn't have all the bells and whistles of estout, but it does have the basic functionality you are looking for (including export to LaTeX): import statsmodels . from statsmodels.iolib.summary2 import summary_col. You can either convert a whole summary into latex via summary.as_latex() or convert its tables one by one by calling table.as_latex_tabular() for each table. import pandas as pd import numpy as np from statsmodels.api import add_constant, OLS from statsmodels.iolib.summary2 import summary_col x = [1, 5, 7, 3, 5] x = add_constant(x) x2 = np.concatenate([x, np.array([[3], [9], [-1], [4], [0]])], 1) x2 = pd.DataFrame(x2, columns=['const','b','a']) # ensure that columns are not in alphabetical order y1 = [6, 4, 2, 7, 4] y2 = [8, 5, 0, 12, 4] reg1 = … By default, the summary() method of each model uses the old summary functions, so no breakage is anticipated. If the dependent variable is in non-numeric form, it is first converted to numeric using dummies. not specified will be appended to the end of the list. That seems to be a misunderstanding. Summarize multiple results instances side-by-side (coefs and SEs), results : statsmodels results instance or list of result instances, float format for coefficients and standard errors summary_col: order/rename regressors in the row index; http://nbviewer.ipython.org/4124662/ What's in here: Summary class: smry = Summary() Convert user input to DataFrames: smry.add_dict(), smry.add_df(), smry.add_array() DataFrame -> SimpleTables -> Output: … We do a brief dive into stats-models showing off ordinary least squares (OLS) and associated statistics and interpretation thereof. Statsmodels is a Python module which provides various functions for estimating different statistical models and performing statistical tests First, we define the set of dependent (y) and independent (X) variables. Summarize multiple results instances side-by-side (coefs and SEs) Parameters: results : statsmodels results instance or list of result instances. Users can also leverage the powerful input/output functions provided by pandas.io. summary () .
