Function that performs bootstrap parametric resampling to compute standard errors for the parameter estimates.
The function is no longer maintained. Please look at bootstrap
function.
bootstrap_lm_basic(piv, Pi, Psi, n, B = 100, start = 0, mod = 0, tol = 10^-6)
piv |
initial probability vector |
Pi |
probability transition matrices (k x k x TT) |
Psi |
matrix of conditional response probabilities (mb x k x r) |
n |
sample size |
B |
number of bootstrap samples |
start |
type of starting values (0 = deterministic, 1 = random) |
mod |
model on the transition probabilities (0 for time-heter., 1 for time-homog., from 2 to (TT-1) partial homog. of that order) |
tol |
tolerance level for convergence |
mPsi |
average of bootstrap estimates of the conditional response probabilities |
mpiv |
average of bootstrap estimates of the initial probability vector |
mPi |
average of bootstrap estimates of the transition probability matrices |
sePsi |
standard errors for the conditional response probabilities |
sepiv |
standard errors for the initial probability vector |
sePi |
standard errors for the transition probability matrices |
