transitions {MCMCprecision}

Get matrix of observed transition frequencies

Description

Summarizes a sequence of discrete values by the observed transition frequencies.

Usage

transitions(z, labels, order = 1)

Arguments

z

vector of model indices (numerical or character)

labels

fixed labels for models that should be included in transition matrix, e.g., labels=1:20 or c("m1","m2",...)

order

order of the transition table. If order=1, a matrix with transition frequencies from z[t+1] is returned. If order=2, a 3-dimensional array is returned with transition frequencies for z[t], z[t+1], and z[t+2].

Value

a square matrix with transition frequencies

Examples

P <- matrix(c(.9,.1,0,
              .1,.6,.3,
              .2,.3,.5), 3, byrow=TRUE)
z <- rmarkov(2000, P)
transitions(z)
transitions(z, order = 2)
