Detailed Description
Defines the combined power_tempered likelihood class. This takes a generic combined likelihood function and then power tempers its value. This is useful when using a parallel tempering scheme.
Member Function Documentation
|
virtual |
Overloaded parenthesis operator that returns the log-likelihood multiplied by beta of a vector in the parameter space at which the likelihood is to be calculated
Reimplemented from likelihood.
| void set_beta | ( | double | beta | ) |
Sets the inverse temperature for the likelihood functions If not set, then beta = 1.
