getdvda {ROSeq} | R Documentation

## Finds the first derivative of v with respect to a. This first derivative is evaluated at the optimal (a_hat, b_hat).

### Description

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

    getdvda(coefficients, r)

### Arguments
