frequency() Function

Function

frequency( data_array, bins_array )

Uses the bin array to create groups bounded by the elements of the array.

Parameters

Keyword Type Description

data_array

Decimal Array

The set of numbers that will be divided into groups according to bins_array and then counted

bins_array

Decimal Array

The upper (and inclusive) boundaries of the groups into which the elements from the data array will be dispersed.

Returns

Integer Array

Usage considerations

Using the bins_array parameter

The bins_array argument also defines one additional group capturing all numbers greater than the maximum number in bins_array.

Understanding results

The return value represents how many elements from the data array fall into each of these groups.

Examples

For example, a bin array equal to {70, 79, 89} defines four groups:

  • numbers where number <= 70
  • numbers where 70 < number <= 79
  • numbers where 79 < number <=89
  • numbers > 89

frequency({64,74,75,84,85,86,95},{70,79,89}) returns 1*2*3*1
