DatasetGroupBy.
quantile
(self, q, dim=None, interpolation='linear', keep_attrs=None)¶ Compute the qth quantile over each array in the groups and concatenate them together into a new array.
- Parameters
q (float in range of [0,1] (or sequence of floats)) – Quantile to compute, which must be between 0 and 1 inclusive.
dim (…, str or sequence of str, optional) – Dimension(s) over which to apply quantile. Defaults to the grouped dimension.
interpolation ({'linear', 'lower', 'higher', 'midpoint', 'nearest'}) –
This optional parameter specifies the interpolation method to use when the desired quantile lies between two data points
i < j
:linear:
i + (j - i) * fraction
, wherefraction
is the fractional part of the index surrounded byi
andj
.lower:
i
.higher:
j
.nearest:
i
orj
, whichever is nearest.midpoint:
(i + j) / 2
.
- Returns
quantiles – If q is a single quantile, then the result is a scalar. If multiple percentiles are given, first axis of the result corresponds to the quantile. In either case a quantile dimension is added to the return array. The other dimensions are the dimensions that remain after the reduction of the array.
