Specifies transition probability matrix with no restrictions on the rates other than that one of the is equal to one and the others are specified relative to this unit rate. Works for any number of states.
Reversible nucleotide substitution model parameterised by model number
Standard nucleotide substitution model TIM2
Has rates 010232 and equal frequencies
Logable: yes, this can be used in a log.

| type: beast.base.core.Function |
| Rate parameter which defines the transition rate matrix. Only the off-diagonal entries need to be specified (diagonal makes row sum to zero in a rate matrix). Entry i specifies the rate from floor(i/(n-1)) to i%(n-1)+delta where n is the number of states and delta=1 if floor(i/(n-1)) <= i%(n-1) and 0 otherwise. |
