bx: Computation Of The Drift Coefficient

Description Usage Arguments Value

Description

Computation of the drift coefficient

Usage

1
bx(x, fixed, random)

Arguments

x

vector of data

fixed

drift constant in front of X (when there is one additive random effect), 0 otherwise

random

1 if there is one additive random effect, 2 one multiplicative random effect or c(1,2) for 2 random effects

Value

b

The drift is b(x,φ) = φ_1 b_1(x) + φ_2 b_2(x), the output is b_2 except when random c(1,2) then the output is the vector (b_1,b_2)^t
