Hidden Markov Models in R
...when they were in fact correct). Once the person achieves the criterion of 9/10 correct responses the contigencies reverse. I am confused on how to set up my states, symbols, starting probabilities, transition probabilities, and emission probabilities in R. This is what I have so far. hmm <- initHMM(c("stay", "switch"), c("correct", "incorrect"), c(.5, .5), matrix(c(.9, .1, .1, .9),2), matrix(c(.2, .8, .8, .2), 2)) dat$test <- ifelse(dat$Slide1_ACC == 0, "incorrect", "correct") viterbi(hmm, dat$test) The sequence of observation...
