Struct PmlVariance 

pub struct PmlVariance {
    pub subject: f64,
    pub cell: f64,
}

The two variance components, held on nebula’s own scale.

subject means different things in the two solvers: the C++ reads the same sigma[0] slot differently in opt_pml and opt_pml_nbm.

Fields

subject: f64

nebula’s sigma[0].

For opt_pml this is log(1 + sigma^2), the log of one plus the squared coefficient of variation of the subject-level gamma random effect; the solver derives alpha = 1 / (e^s - 1) and lambda = 1 / (sqrt(e^s) (e^s - 1)) from it. For opt_pml_nbm it is the variance of the normal random effect on the log scale, used as is.

cell: f64

nebula’s sigma[1], its gamma: the cell-level negative binomial size, the reciprocal of the cell-level overdispersion.
