Description

What is your issue?

Hi, I am trying to compute the moving average like the following in pandas using DataArray.rolling_exp:

df.ewm(alpha=0.9, ignore_na=True, adjust=True).mean()

does anyone know how to specify ignore_na and adjust in DataArray.rolling_exp?

Thanks!

Research direction

Start by reading the DataArray.rolling_exp API and comparing it with pandas' df.ewm(alpha=0.9, ignore_na=True, adjust=True).mean() example. Trace how rolling exponential options are exposed and check the existing tests or documentation around this entry point. Done means the handling of ignore_na and adjust is clearly supported or documented.
