Description

For internal use only.

Usage

bm_loglik_trio(a, v, d1, d2, s, t1, t2, sigma2x, sigma2y, areas, daughter_ids, nGQ)

Arguments

a	vector with ancestor value (x & y).
v	vector with current point being evaluated (x & y).
d1	vector with first daughter value (x & y).
d2	vector with second daughter value (x & y).
s	time separating v from ancestor.
t1	time separating v from first daughter.
t2	time separating v from second daughter.
sigma2x	current value for sigma2x.
sigma2y	current value for sigma2y.
areas	polygonal areas, to save time and not recalculate.
daughter_ids	the ids of the daughters of the node.
nGQ	degree of the one-dimensional Gauss-Legendre quadrature rule (default = 20) as given by polyCub.SV in package polyCub.

Value

loglikelihood of v according to Brownian motion.
