BETAINV

BETAINV 函數會傳回指定 Beta 分配累加機率值的反函數。所有引數為數字值。

BETAINV(機率, alpha, beta, x 下限, x 上限)

機率： 與分佈相關的機率。機率必須大於 0 並小於 1。

alpha： 分佈的形狀參數。 alpha 必須大於 0。

beta： 分佈的形狀參數。 beta 必須大於 0。

x 下限： 特定 x 值或機率的下限或最低界限（可留空）。 x 下限必須小於或等於機率。如省略 x 下限，則會使用 0。

x 上限： 特定 x 值或機率的上限或最高界限（可留空）。 x 上限必須大於或等於機率。如省略 x 上限，則會使用 1。

範例

=BETAINV(0.5, 1, 2, 0.3, 2) 會傳回 0.797918471982869。

=BETAINV(0.99, 1, 2, 0, 2) 會傳回 0.9。

=BETAINV(0.1, 2, 2, 0, 2) 會傳回 0.391600211318183。
