bootstrapfun | R Documentation |
This function simulates the data under the null hypothesis of a Gaussian HMM and compute the Cramér-von Mises test statistic.
bootstrapfun(mu, sigma, Q, max_iter, prec, n)
mu |
vector of means for each regime (r x 1); |
sigma |
vector of standard deviations for each regime (r x 1); |
Q |
transition probality matrix (r x r); |
max_iter |
maximum number of iterations of the EM algorithm; suggestion 10 000; |
prec |
precision (stopping criteria); suggestion 0.0001; |
n |
length of the time series. |
f |
values of the density function at time n+k |
w |
weights of the mixture |
