Description

Currently ewm_mean_by and ewm_mean are both available as expressions and series computations, where ewm_mean calculates weights its for each value in the sequence and ewm_mean_by calculates using a time-based moving average. However, there is no corresponding time based ewm_std_by or ewm_var_by. This request is for the implementation of time-based ewm_std_by and ewm_var_by.
