For an example, I have dataframe

> a b
> 10 50
> 20 30
> 30 90
> 40 10
> 50 70

I want to find a correlation by using pandas.core.window.EWM.cor method

I have tried to find an example to use as in documentation

EWM.corr(other=None, pairwise=None, **kwargs)

so i try to use by

df['ab_corr'] = pandas.core.window.EWM.corr(other=df.b)

TypeError: corr() missing 1 required positional argument: 'self'

I think it requires df.a but I don't know the correct way to use this method.
