maxframe.dataframe.DataFrame.pct_change#

DataFrame.pct_change(periods=1, fill_method='pad', limit=None, freq=None, **kwargs)#

Percentage change between the current and a prior element.

Computes the percentage change from the immediately previous row by default. This is useful in comparing the percentage of change in a time series of elements.

Parameters:

  • periods (int, default 1) – Periods to shift for forming percent change.

  • fill_method (str, default 'pad') – How to handle NAs before computing percent changes.

  • limit (int, default None) – The number of consecutive NAs to fill before stopping.

  • freq (DateOffset, timedelta, or str, optional) – Increment to use from time series API (e.g. ‘M’ or BDay()).

  • **kwargs – Additional keyword arguments are passed into DataFrame.shift or Series.shift.

Returns:

chg – The same type as the calling object.

Return type:

Series or DataFrame
