Thanks for contributing an answer to Data Science Stack Exchange! a is generally a Pandas dataframe or a NumPy array. Manually searching for duplicates was not practical. In this guide, we will be building statistical models for predicting a binary outcome, meaning an outcome that can take only two distinct values. The following are 30 code examples for showing how to use statsmodels.api.OLS().These examples are extracted from open source projects. Hi, I'm a new subscriber of this list. This doesn’t seem to be the case here. I recently got this message, too, and I found like user @jason and @user3805082 above that I had duplicate columns in several of the hundreds of dataframes I was trying to concat, each with dozens of enigmatic varnames.

Twitter Error is result of having duplicate columns. Now we perform the regression of the predictor on the response, using the sm.OLS class and and its initialization OLS(y, X) method. So yeah, probably something like 1.6472836292952922e-05 is not interpreted as numeric. This question needs details or clarity.

OLS only supports univariate endog (unless we only want params) So, either make sure endog is univariate, e.g. Returns array_like. I am running a multiple linear regression using backward elimination. First you need to split the dataset into X_opt_train and X_opt_test and y_train and y_test.
