Rolling problem when calculating std for low values

[JoschD]

Pandas rolling std() function will not work for small numbers (i.e. <1e-8), which we might encounter in the error values, from pandas version 1.2.0, see pandas-dev/pandas#37051 and pandas-dev/pandas#39872 .

As we are using this for cleaning purposes in bbq_tools we should replace this by a manual rolling loop.

[JoschD]

Should be fixed in newer pandas versions: pandas-dev/pandas#40505
(This is milestone for version 1.3 so probably this one when it's released)
To be tested!

I guess that will simply make us force != 1.2 in the dependencies then?

[JoschD]

Just tested in pandas 1.3.1 and it works correctly again. So yes, != 1.2 will work!

[JoschD]

We have != 1.2 in the dependencies for this reason. Fixed.
