Bin

This function will categorize or bin an input column such that for N bins, an output column is created with values [1-N] where each value represents some bin.

This transformation supports two binning methods (called "binning_type" in the arguments): ntile and equalwidth.

N-tile

When using ntile binnint the boundaries for the bins are calculated such that each bin will receive an almost equal number of elements. It will create a new column called {{column}}_{{bin_count}}_NTB. This ensures that multiple equal-weight binning operations will produce column names that don't overlap.

Equal Width

The equalwidth method will calculate the boundaries of the bins such that they will be of equal width based on the min and max value within the source column. This transformation will create a new column called {{column}}_{{bin_count}}_EWB. This ensures that multiple equal-weight binning operations will produce column names that don't overlap.

Parameters

Name	Type	Description	Is Optional
type	string	binning algorithm to use; must be ntile or equalwidth
bin_count	int	the number of equal-width bins to use
column	column	which column to bucket

Example

ds = rasgo.get.dataset(id)

ds2 = ds.bin(type='equalwidth', bin_count=6, column='DAILY_HIGH_TEMP')
ds2.preview()
