pyarrow.compute.approximate_median#
- pyarrow.compute.approximate_median(array, /, *, skip_nulls=True, min_count=1, options=None, memory_pool=None)#
Approximate median of a numeric array with T-Digest algorithm.
Nulls and NaNs are ignored. A null scalar is returned if there is no valid data point.
- Parameters:
- arrayArray-like
Argument to compute function.
- skip_nullsbool, default
True Whether to skip (ignore) nulls in the input. If False, any null in the input forces the output to null.
- min_count
int, default 1 Minimum number of non-null values in the input. If the number of non-null values is below min_count, the output is null.
- options
pyarrow.compute.ScalarAggregateOptions, optional Alternative way of passing options.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
