This function returns the upper tail probability of a truncated central chi-squared distribution
at quantile q
.
1 | TChisqSurv(q, df, E, approx = FALSE)
|
q |
the quantile. |
df |
the degree of freedom. |
E |
the truncation set, an "Intervals" object or a matrix where rows represents a union of disjoint intervals. |
approx |
should the approximation algorithm be used? Default is |
Let X be a central chi-squared random variable with df
degrees of freedom. Truncating
X to the set E is equivalent to conditioning on {X \in E}. So this function
returns P(X ≥ q | X \in E).
This function returns the value of the survival function evaluated at quantile q
