Respected Sir, I am working on Hidden Markov Models for count data. My data consist of number of new infectives in a ward per month. I have data for about 50 months. How can I fit a Hidden Markon Model to my data. I am using 'repeated' package('hidden' and 'chidden' arguments). I would like to know how can I estimate the initial values of the parameters(mu and pgamma). I have a 27 state Markov Chain.Can you tell me a standard book on HMM which have the corresponding R codes. I will be grateful for the help extended. Thanking You, Yours Faithfully, Regina -- regina.verghis@gmail.com Regina M.Verghis, Post Graduate Student Department of Biostatistics, Christian Medical College, Vellore, Tamilnadu- 632002 India.
