calc_loglik: Calculates marginal likelihood
In SAVER: Single-Cell RNA-Seq Gene Expression Recovery

Description Usage Arguments Details Value

Calculates the marginal likelihood given the prediction under constant coefficient of variation (a), Fano factor (b), and variance (k).

calc.loglik.a(a, y, mu, sf)

calc.loglik.b(b, y, mu, sf)

calc.loglik.k(k, y, mu, sf)

`a, b, k`	Prior parameter.
`y`	A vector of observed gene counts.
`mu`	A vector of predictions from `expr.predict`.
`sf`	Vector of normalized size factors.

calc.loglik.a returns the shifted negative log-likelihood under constant coefficient of variation. calc.loglik.b returns the shifted negative log-likelihood under constant Fano factor. calc.loglik.k returns the shifted negative log-likelihood under constant variance.

A shifted negative marginal log-likelihood.
