Select Belief System

 

Print this Topic Previous pageReturn to chapter overviewNext page

The belief system for adaptive learning, also known as the perceived law of motion (PLM), is by default constructed as AR(2) processes with a constant for each forward looking variable. This PLM is known as the naive system in YADA. The user can also construct a so called belief system file with an user determined PLM. This file is a matlab function which accepts certain input variables and provides an output variable that allows YADA to set up the desired PLM. YADA restrict the use of a PLM to have at most two lags and can only include the deterministic variables as well as lags of the state variables in the model.

 

Additional Information

A detailed discussion about the construction of the perceived law of motion in the adaptive learning framework can be found in Section 17.1.2 of the YADA Manual.
An example file is located in the directory "example\AnSchorfheide" directly below the base directory for YADA. The file is simply called "ASBeliefSystemFile.m".
An additional example file can be found in the "SlobodyanWouters" directory in the "example" directory. This file is called "SloWoREStyleBeliefSystemFile.m".
