This function calculates the percentile rank for each non-null value in a single-valued numeric or date column. Percentile ranks are assigned based on the relative position of each value in the sorted column, with results ranging [0, 1). Null values are preserved and do not affect the ranking. The function does not support multi-valued columns.

​
Usage

Inputs & Outputs

The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced by name e.g. "churn-clf").

​
Configuration

The following parameters can be used to configure the behaviour of the step by including them in a json object as the last “input” to the step, i.e. step(..., {"param": "value", ...}) -> (output).
