The number of bins can be set using the :py:attr:`numBuckets` parameter. - It is possible that the number of buckets used will be less than this value, for example, if - there are too few distinct values of the input to create enough distinct quantiles. Note also - that NaN values are handled specially and placed into their own bucket. For example, if 4 - buckets are used, then non-NaN data will be put into buckets(0-3), but NaNs will be counted in - a special bucket(4). The bin ranges are chosen using an approximate algorithm (see the documentation for :py:meth:`~.DataFrameStatFunctions.approxQuantile` for a detailed description). The precision of the approximation can be controlled with the |
