Consensus¶

These functions analyze agreement, voting patterns, and frequency distributions across collections of responses.

majority_vote¶

majority_vote(list)

Returns the most common element in a list.

Parameters:

Returns: The value that appears most frequently.

let winner = majority_vote(["yes", "no", "yes", "yes", "no"]);
// winner = "yes"

consensus_threshold(list, threshold)

Checks whether the most common element in a list meets a frequency threshold.

Parameters:

Returns: A record with three fields:

let result = consensus_threshold(responses, 0.8);
// result = {"consensus": true, "value": "yes", "frequency": 0.85}

mode(list)

Returns the statistical mode (most frequent value) of a list.

Parameters:

Returns: The most frequent value.

let m = mode([1, 2, 2, 3, 3, 3]);
// m = 3

agreement_rate(list)

Computes the frequency of the most common element as a proportion of the total list length.

Parameters:

Returns: A number between 0.0 and 1.0.

let rate = agreement_rate(["yes", "yes", "no", "yes"]);
// rate = 0.75

unique_values(list)

Returns the distinct values in a list, preserving their order of first appearance.

Parameters:

Returns: A list of unique values.

let uniq = unique_values(["a", "b", "a", "c", "b"]);
// uniq = ["a", "b", "c"]

value_counts(list)

Counts the frequency of each distinct value in a list.

Parameters:

Returns: A record mapping each value to its count.

let counts = value_counts(["yes", "no", "yes", "yes"]);
// counts = {"yes": 3, "no": 1}
