  1. Why is unexpected keyword argument 'typ' error thrown?

    For typical integer values of p, d, q and a list of numbers, rollRate, the following code: fit = statsmodels.api.tsa.ARIMA(rollRate, (p,d,q)).fit() forecast = fit.predict(start=len(rollRate), ...Learn More
  2. How to create mosaic plot from Pandas dataframe with Statsmodels library?

    Using Python 3.4, Pandas 0.15 and Statsmodels 0.6.0, I try to create a mosaic plot from a dataframe as described in the Statsmodels documentation. However, I just don't understand how the input has to be format...Learn More
  3. Statsmodels - OLS Clustered Standard Errors (not accepting Series from DF?)

    I am running an analysis that could benefit from clustering by BEA regions. I have not used the clustered standard error option in Statsmodels before, so I am unclear of whether or not I am messing up the synt...Learn More
