    cols? correction? df expected lowExpected pValue rows? statistic test
    cols?: string[]
    correction?: boolean

    Yates continuity correction applied (2×2 tables only).

    df: number
    expected: number[] | number[][]

    Expected counts under H0 (matrix for independence, vector for goodness of fit).

    lowExpected: boolean

    True when any expected count is below 5 — the chi-square approximation is then questionable.

    pValue: number
    rows?: string[]

    Row / column labels when built from DataFrame columns.

    statistic: number
    test: "chi-square independence" | "chi-square goodness of fit"
