RNA.M16A — Exchangability matrix on doublets constructed from nucleotide exchange rates

Usage

RNA.M16A(aS: Double, aD: Double, b: Double, g: Double, e: Double, pi: Map<String,Double>, a: a) → CTMC<a>

Arguments

Underlined names in default expressions refer to other arguments. A default beginning with ~ specifies a prior distribution.

aS:

Exchange rate: 1 change, match <-> match

Default: ~LogNormal(log(2),0.25)

aD:

Exchange rate: 2 changes, match <-> match, both transitions

Default: ~LogNormal(log(2),0.25)

b:

Exchange rate: 2 changes, match <-> match, both transversions

Default: ~LogNormal(log(2),0.25)

g:

Exchange rate: 1 changes, match <-> mismatch

Default: ~LogNormal(log(2),0.25)

e:

Exchange rate: 1 changes, mismatch <-> mismatch

Default: ~LogNormal(log(2),0.25)

pi:

Doublet frequencies

Default: ~SymmetricDirichletOn(letters(a),1)

a:

The Doublets alphabet

Default: The alphabet in the current context

Original default expressions
pi
~SymmetricDirichletOn(letters(@a),1)
a
get_state(alphabet)

Description

Exchangability matrix for rna stems that allows 2 simultaneous changes.

Note the exchange rate for double changes involving a mismatch is 0.
