Description

Recursively compute the denominator of the individual conditional likelihood function for the Quadratic Exponential Model, adapted from Krailo & Pike (1984).

Usage

1
quasi_sym(eta,s,dyn=FALSE,y0=NULL)

Arguments

eta

individual vector of products between covariate and parameters

s

total score of the individual

dyn

TRUE if in the dynamic version; FALSE for the static version (by default)

y0

Individual initial observation for dynamic models

Value

f

value of the denominator

d1

first derivative of the recursive function

dl1

a component of the score function

D2

second derivative of the recursive function

Dl2

a component of the Hessian matrix
