public class GammaRegularizedPInverse extends AbstractBivariateRealFunction
s > 1, we use the asymptotic inversion method.s <= 1, we use an approximation of P(s,x) together with a higher-order Newton like method.HalleyRoot.
The R equivalent function is qgamma. E.g., qgamma(u, s, lower=TRUE).Function.EvaluationException| Constructor and Description |
