pandas.core.window.Expanding.quantile

Calculate the expanding quantile.

param quantile

float

Quantile to compute. 0 <= quantile <= 1.

param interpolation

{‘linear’, ‘lower’, ‘higher’, ‘midpoint’, ‘nearest’}

New in version 0.23.0.

This optional parameter specifies the interpolation method to use, when the desired quantile lies between two data points i and j:

• linear: i + (j - i) * fraction, where fraction is the

  fractional part of the index surrounded by i and j.

• lower: i.

• higher: j.

• nearest: i or j whichever is nearest.

• midpoint: (i + j) / 2.

  **kwargs: For compatibility with other expanding methods. Has no effect on the result.

return

Series or DataFrame Returned object type is determined by the caller of the expanding calculation.
