Struct NuLift 

pub(crate) struct NuLift {
    c1: f64,
    c2: f64,
}

The ν-derivatives of a unit-variance t at its passive point, for lifting its CDF, density and quantile jointly in (z, ν).

The log-density is g = c(ν) − (ν+1)/2·(ln q − ln(ν−2)), q = ν − 2 + z², c(ν) = ln Γ((ν+1)/2) − ln Γ(ν/2) − ½·ln(π(ν−2)); so g_ν = c′ − ½(ln q − ln(ν−2)) − (ν+1)/2·(1/q − 1/(ν−2)) and g_νν = c″ − (1/q − 1/(ν−2)) + (ν+1)/2·(1/q² − 1/(ν−2)²), c′, c″ read off the gamma ratio in Jet2.

Fields

c1: f64

c′(ν).

c2: f64
