bm_propose_trio: MCMC proposal for a 2-dimensional point with two daughters and one ancestor nodes

Description

For internal use only.

Usage

bm_propose_trio(a, d1, d2, s, t1, t2, sigma2x, sigma2y)

Arguments

a
vector with current ancestor value (x & y).
d1
vector with current first daughter value (x & y).
d2
vector with current second daughter value (x & y).
s
time separating node being proposed from ancestor.
t1
time separating node being proposed from first daughter.
t2
time separating node being proposed from second ancestor.
sigma2x
current value for sigma2x.
sigma2y
current value for sigma2y.

Value

a list with 3 objects. The vector proposal ($value), the logforward probability ($logfwdprob), and the logbackward probability ($logbwdprob).
