Attributes classes_ ndarray of shape (n_classes, ) A list of class labels known to the classifier. The OLS() function of the statsmodels.api module is used to perform OLS regression. Stata also reports it for the linear regression. The original array with a constant (column of ones) as the first or add_constant (data[, prepend, has_constant]) Add a column of ones to an array. I guess we should initialize the mle_retvals as an empty dict, but then we don't have the converged info, which might cause another exception in summary (set converged=nan?). multiple regression, not multivariate), instead, all works fine. Canonically imported using import statsmodels.formula.api as smf The API focuses on models and the most frequently used statistical test, and tools. Try the command dir(ngram) and see all the objects and classes in the module and find what you want.

Variables in y0 and y1 are assumed to be integrated of order 1, I(1). @jeffmax Thanks for the explanation.. We don't have the simple ANOVA table associated with a regression. Are the statsmodels versions identical? "AttributeError: module 'statsmodels.sandbox' has no attribute 'stats'" I've just spent the past two hours trying to get it to work. Statsmodels is built on top of NumPy, SciPy, and matplotlib, but it contains more advanced functions for statistical testing and modeling that you won't find in numerical libraries like NumPy or SciPy.. Statsmodels tutorials. Robust estimator instance instantiated. This uses the augmented Engle-Granger two-step cointegration test. These examples are extracted from open source projects.

Python 3 version of the code can be obtained by running 2to3.py over the entire statsmodels source. A nobs x k array where nobs is the number of observations and k is the number of regressors. $\begingroup$ It is the exact opposite actually - statsmodels does not include the intercept by default. R-squared of the model. nobs: float The number of observations n pinv_wexog: array The pseudoinverse of the design / exogenous data array. True and the constant is prepended rather than appended. This module allows estimation by ordinary least squares (OLS), weighted least squares (WLS), generalized least squares (GLS), and feasible generalized least squares with autocorrelated AR(p) errors. It complements SciPy's stats module. See statsmodels.tools.add_constant.

If sigma is a scalar, it is assumed that sigma is an n x n diagonal matrix with the given scalar, sigma as the value of each diagonal element. Since I work at a lab that was founded in 1910, and still retains data from some of those early studies, the ability to document the provenance of the analytical tools is encouraged.
