pyarrow.compute.approximate_median¶
-
pyarrow.compute.approximate_median(array, *, memory_pool=None, options=None, skip_nulls=True, min_count=1)¶ 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
array (Array-like) – Argument to compute function
memory_pool (pyarrow.MemoryPool, optional) – If not passed, will allocate memory from the default memory pool.
options (pyarrow.compute.ScalarAggregateOptions, optional) – Parameters altering compute function semantics.
skip_nulls (optional) – Parameter for ScalarAggregateOptions constructor. Either options or skip_nulls can be passed, but not both at the same time.
min_count (optional) – Parameter for ScalarAggregateOptions constructor. Either options or min_count can be passed, but not both at the same time.
