Fitting Models to Data¶
Model-Fitting Methods in Fitr¶
Fitr implements several model-fitting methods:
Method | Function | Reference |
---|---|---|
EM with Laplace Approximation | fitr.EM() |
[Huys2011] |
Empirical Priors | fitr.EmpiricalPriors() |
[Gershman2016] |
Markov Chain Monte-Carlo (Stan) | fitr.MCMC() |
[StanDevs] |
Here, “EM” refers to Expectation-Maximization.
