Percentile-modified rank (Gastwirth) two-sample test (Gibbons Ch 8.3.3)

Trims central ranks; only tail ranks contribute. Score: a_i = max(R_i - (1-q)(N+1), 0) - max(q(N+1) - R_i, 0)

Usage

morie_percentile_modified_rank(x, y, q = 0.25)

Arguments

x, y

Numeric vectors.

q

Tail fraction in (0, 0.5). Default 0.25.

Value

Named list: statistic, p_value, z, n, m, q.
