WebNov 19, 2024 · The quantile function QX(p) Q X ( p) is defined as the smallest x x, such that F X(x) = p F X ( x) = p: QX(p) = min{x ∈ R F X(x) = p}. (4) (4) Q X ( p) = min { x ∈ R F X ( x) = p }. Thus, we have QX(p) = −∞ Q X ( p) = − ∞, if p = 0 p = 0. When p > 0 p > 0, it holds that QX(p) = F −1 X (x). (5) (5) Q X ( p) = F X − 1 ( x). WebVarious implementations of Q-Q plots exist in R.
