[pystatsmodels] Abbreviations: StatsModels handling NaN

[h***@gmail.com]

In StatsModels there are keywords to specify how to deals with NaNs.

'none' := no checks for missing values

'drop' := drops missing values

'raise' := raises an error

But there is another keyword: 'conservative'. I don't understand what this
does.

Here is the documentation, but it is not explained what is does:
https://www.statsmodels.org/dev/generated/statsmodels.tsa.stattools.acf.html

I'm especcially interested in what is means in the contect of
Autocorrelation.

Thanks!
