Arguments

• x: an object of class dlm.
• value: a numeric matrix (or vector for m0).

Details

Missing or infinite values are not allowed in value. The dimension of value must match the dimension of the current value of the specific component in x

Returns

For the assignment forms, the updated dlm object.

For the other forms, the specific component of x.

set.seed(222)
mod <- dlmRandom(5, 6)
all.equal( FF(mod), mod$FF )
all.equal( V(mod), mod$V )
all.equal( GG(mod), mod$GG )
all.equal( W(mod), mod$W )
all.equal( m0(mod), mod$m0 )
all.equal( C0(mod), mod$C0)
m0(mod)
m0(mod) <- rnorm(6)
C0(mod)
C0(mod) <- rwishart(10, 6)
### A time-varying model
mod <- dlmModReg(matrix(rnorm(10), 5, 2))
