}

Result of percentile-based process capability analysis.

Fields

cp_star: Option<f64>

Cp* = (USL − LSL) / (X₉₉.₈₆₅ − X₀.₁₃₅). Requires both limits.

cpk_star: Option<f64>

Cpk* = min(Cpu*, Cpl*). Requires at least one limit.

cpu_star: Option<f64>

Cpu* = (USL − median) / (X₉₉.₈₆₅ − median). Requires USL.

cpl_star: Option<f64>

Cpl* = (median − LSL) / (median − X₀.₁₃₅). Requires LSL.

median: f64

Sample median.

percentile_lower: f64

0.135th percentile value (lower natural process limit).

percentile_upper: f64

99.865th percentile value (upper natural process limit).
