[−][src]Function r_stats::weibull_cdf
pub fn weibull_cdf(
x: f64,
shape: f64,
scale: f64,
lower_tail: bool,
log_p: bool
) -> f64
Evaluate the culmulative distribution function of the Weibull distribution.
If lower_tail
is true, the integral from -∞
to x
is evaluated, else the
integral from x
to ∞
is evaluated instead. "Usual" behaviour corresponds to
true
. Using lower_tail = false
gives higher numerical accuracy than performing the
calculation 1 - result
on lower_tail = true
(when the result is close to 1).
If log_p
is true, the natural logarithm of the value will be returned, with potentially
higher numerical accuracy than calling .ln()
on the result.
