pred.mean: Prediction mean

Description

The mean of the prediction distribution

Usage

# S4 method for kalmand_pomp
pred.mean(object, vars, ...)

# S4 method for pfilterd_pomp pred.mean(object, vars, ...)

Arguments

object

result of a filtering computation

vars

optional character; names of variables

...

ignored

Details

The prediction distribution is that of $$X(t_k) \vert Y(t_1)=y^*_1,\dots,Y(t_{k-1})=y^*_{k-1},$$ where \(X(t_k)\), \(Y(t_k)\) are the latent state and observable processes, respectively, and \(y^*_k\) is the data, at time \(t_k\).

The prediction mean is therefore the expectation of this distribution $$E[X(t_k) \vert Y(t_1)=y^*_1,\dots,Y(t_{k-1})=y^*_{k-1}].$$
