Description Usage Arguments Value Examples
Calculates the estimated optimal average coverage CIs, and
tuning parameters associated with those CIs, using the function gnB_norm
.
1 | ACI_aux(x_vec, sig_vec, alpha, Jn, lam_init, Jn2)
|
x_vec |
a vector of observed values. |
sig_vec |
a vector of individual standard deviations. |
alpha |
a desired level of non-coverage. |
Jn |
the order of series approximation; do not specify its value when using the simple estimator. |
lam_init |
the candidate vector of minimum shrinkage factors to be used; do not specify its value when using the simple estimator. |
Jn2 |
the total order of polynomial approximation. |
a list with four components; lam_opt
gives the value of the
optimal shrinkage factor, chi_opt
gives the value of the normalized half-length
associated with the optimal shrinkage factor, and CI_l
and CI_u
gives the vector of
lower and upper ends of the confidence intervals, respectively.
