oneWayAnova
oneWayAnova(
groups):OneWayAnovaResult
Defined in: one-way-anova.ts:39
One-way analysis of variance: whether several groups share a common mean.
The two sums of squares are accumulated exactly. Their terms are deviations
from a mean, so they straddle zero by construction and a naive running total
can cancel away every significant bit of either accumulator — the same reason
linearRegressionSlope compensates.
Named oneWayAnova rather than anova because the one-way layout is a
genuine restriction, not an implementation detail: a two-way or repeated
measures design takes a different input shape and answers a different
question, and would be a different function rather than an option here.
Parameters
