getd: Finds the double derivative of A

In krishan57gupta/ROSeq: Modeling expression ranks for noise-tolerant differential expression analysis of scRNA-Seq data

Description

Finds the double derivative of A with with respect to a, (a, b), b , (a, b) in respective templates from right to left. This first derivative is evaluated at the optimal (a_hat, b_hat). u1, v and u2 constitute the equations required for evaluating the first and second order derivatives of A with respect to parameters a and b

Usage

getd(u1, v, du1da, dvda)

Arguments

u1	u1
v	v
du1da	First derivative of u1 with respect to parameter a
dvda	First derivative of v with respect to parameter a

Value

d2logAda2
