pyarrow.compute.winsorize#

pyarrow.compute.winsorize(array, /, lower_limit, upper_limit, *, options=None, memory_pool=None)#

Winsorize an array.

This function applies a winsorization transform to the input array so as to reduce the influence of potential outliers. NaNs and nulls in the input are ignored for the purpose of computing the lower and upper quantiles. The quantile limits can be changed in WinsorizeOptions.

Parameters:

arrayArray-like

Argument to compute function.

lower_limitfloat, between 0 and 1

The quantile below which all values are replaced with the quantiles value.

upper_limitfloat, between 0 and 1

The quantile above which all values are replaced with the quantiles value.

optionspyarrow.compute.WinsorizeOptions, optional

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

If not passed, will allocate memory from the default memory pool.
