In the version of this article initially published in the Methods section “E-step” several variables appeared as m which should have been i. The sentence “The forward step identifies the probability \(a_m\left( t \right) = P\left( {Y_1 = y_1, \ldots ,Y_t,Z_t = m|{\mathbf{\theta }}} \right)\) of observing \(Y = y_1,y_2, \ldots ,y_t\) and, assuming there are N total states, of being in state m at time t by iteratively computing as follows:” should have read, “The forward step identifies the probability \(a_i\left( t \right) = P\left( {Y_1 = y_1, \ldots ,Y_t,Z_t = i|{\mathbf{\theta }}} \right)\) of observing \(Y = y_1,y_2, \ldots ,y_t\) and, assuming there are N total states, of being in state i at time t by iteratively computing as follows:” and errors appears in equations (8) and (9). The errors have been corrected in the PDF and HTML versions of this article.
