exact_inference_backwards: Performs exact inference smoothing with the GDBN over a data set

Description

Given a bn.fit object, the size of the net and a data.set, performs exact smoothing over the initial evidence taken from the data set. Take notice that the smoothing is done backwards in time, as opposed to forecasting.

Usage

exact_inference_backwards(dt, fit, size, obj_vars, ini, len, prov_ev)

Arguments

dt

data.table object with the TS data

fit

bn.fit object

size

number of time slices of the net

obj_vars

variables to be predicted. Should be in the oldest time step

ini

starting point in the data set to smooth

len

length of the smoothing

prov_ev

variables to be provided as evidence in each forecasting step. Should be in the oldest time step

Value

the results of the smoothing
