This function merges states i_1, …, i_j into a
new, single state i_1 by adding corresponding
columns of the weight matrix (mathbf{W}_{i_1} =
mathbf{W}_{i_1} + … + mathbf{W}_{i_j}) and
removing columns i_2, …, i_j.
Usage
merge_states(states, weight.matrix)
Arguments
states
vector of length 1 ≤q j ≤q K with
the states i_1, …, i_j subset lbrace 1,
…, K
brace that should be merged; no repeating
state labels allowed.
weight.matrix
N \times K weight matrix
Examples
set.seed(10)
WW <- matrix(c(rexp(1000, 1/10), runif(1000)), ncol = 5, byrow = FALSE)
WW <- normalize(WW)
image2(WW, density = TRUE)
## Not run:
merge_states(c(1, 1, 5), WW) # error since states were repeated
## End(Not run)
WW_new <- merge_states(c(1, 3, 5), WW)
par(mfrow = c(1, 2), mar = c(1, 1, 2, 1))
image2(WW, main = paste(ncol(WW), "states"), legend = FALSE)
image2(WW_new, main = paste(ncol(WW_new), "states"), legend = FALSE)
