Chi2ContingencyResult.GetHashCode

A hash consistent with the equality, in constant time.

public int GetHashCode()

Returns — a hash over the scalars and the number of rows.

Example — equal results hash alike.

using Lodestar.Stats;

Chi2ContingencyResult left = new(1.5, 0.2, 1, [1.0, 2.0], [3.0, 4.0](/CyrilB1531/lodestar/wiki/1.0,-2.0],-[3.0,-4.0));
Chi2ContingencyResult right = new(1.5, 0.2, 1, [1.0, 2.0], [3.0, 4.0](/CyrilB1531/lodestar/wiki/1.0,-2.0],-[3.0,-4.0));

bool alike = left.GetHashCode() == right.GetHashCode();  // => True

Remarks — the table contributes its row count, never its frequencies. Equal results agree on that count, and walking the table would make hashing cost what the test itself cost.

Applies to — net10.0, netstandard2.0.
