Title: FEATURE Request: Option to have a default log likelihood formulation
Post by: maitreyakurumbhati on March 12, 2021, 06:33:35 PM

Would it be possible to have a default log likelihood formulation i.e. a gaussian wherein they user can perform the inverse problem without having to write a separate script that defines the log likelihood?

Currently, the TMCMC algorithm in the UCSD_UQ engine requires the users to specify the log-likelihood function in a script. This will be made optional and a Gaussian log-likelihood will be made the default. This has been added to our list of tasks.

Bayesian inference using the Dakota engine assumes that the log-likelihood is Gaussian, and does not require the user to write a separate script defining the log-likelihood function.
