- pandas.stats.moments.expanding_quantile(arg, quantile, min_periods=1, freq=None)¶
Expanding quantile.
Parameters : arg : Series, DataFrame
quantile : float
0 <= quantile <= 1
min_periods : int, default None
Minimum number of observations in window required to have a value (otherwise result is NA).
freq : string or DateOffset object, optional (default None)
Frequency to conform the data to before computing the statistic. Specified as a frequency string or DateOffset object.
