the most frequent vote cast for every id; MATLAB’s majorityVote

Syntax

vote, numVotes = majorityVote([1, 1, 1, 1, 1, 2, 3, 2, 3, 2, 3], [5, 9, 5, 9, 9, 4, 1, 4, 2, 4, 1])

The most frequent vote per id.

vote, numVotes = majorityVote([1, 1, 2, 2, 3], [5, 5, 4, 7, 1], strict=True)

A vote only where all agree.

vote, numVotes = majorityVote([1, 1, 2], [5, 9, 4], maxId=5)

A row for every id up to 5.

vote, numVotes = majorityVote([1, 1, 1], [5, 9, 9], weights=[3, 1, 1])

The vote of the largest summed weight.

Description

The votes are grouped by their id, and every id from 1 to maxId gets one row, at position id - 1: the vote cast most often for it, the smallest of a tie, and NaN for an id without votes. Votes that are NaN and ids below 1 are left out.

Input

`id`	integer array, the id every vote is cast for, from 1
`votes`	array of the same length, the votes, positive integers

Keywords

keyword	default	description
`maxId`	`None`	the number of rows, by default the largest id
`strict`	`False`	give a vote only to an id whose votes all agree, NaN to the others
`weights`	`None`	array of the length of votes, a weight for every vote; the vote of the largest summed weight wins

Output

`vote`	array of maxId entries, the winning vote of every id, NaN where there is none
`numVotes`	array of maxId entries, how often the winning vote was cast; with weights the lead of the winning vote, its weight over the sum of its weight and the second’s
