I'm struggling with forecasting out of sample values with an ARMAX model. Fitting the model works fine. armax_mod31 = sm.tsa.ARMA(endog = sales, order = (3,1), exog = media).fit() armax_mod31.fi...

I tried to calculate logical regression. I have the data as csv file. it looks like node_id,second_major,gender,major_index,year,dorm,high_school,student_fac 0,0,2,257,2007,111,2849,1 1,0,2,271,2...

I am trying to learn an ordinary least squares model using Python's statsmodels library, as described here. sm.OLS.fit() returns the learned model. Is there a way to save it to the file and reload...

I'm not sure why I'm getting slightly different results for a simple OLS, depending on whether I go through panda's experimental rpy interface to do the regression in R or whether I use statsmodels...

I need some advice on selecting statistics package for Python, I've done quite some search, but not sure if I get everything right, specifically on the differences between statsmodels and sci...

I'm building a WLS (statsmodels.formula.api.wls) model using the statsmodels formulas API (from patsy) and I'm using interactions between factors. Some of these are predictive whereas others are no...

I have been using ECDF (empirical cumulative distribution function) from statsmodels.distributions to plot a CDF of some data. However, ECDF uses a step function and as a consequence I get jagged-l...

I am trying to use python to compute multiple linear regression and multiple correlation between a response array and a set of arrays of predictors. I saw the very simple example to compute multipl...

I've been learning Python for several months but now finding some problems with my 2.7 installation as I've looked into modules such as nltk. However, when I want to list modules using help ("...

I want to forecast timeseries data. I read in previous posts that module statsmodels has the required tool for using ARMA method for forecasting which is exactly the one I have been looking for. In...

I am trying to run a Augmented Dickey-Fuller test in statsmodels in Python, but I seem to be missing something. This is the code that I am trying: import numpy as np import statsmodels.tsa.statto...
