beta_AD | R Documentation |
Caculate the estimators of beta on the A-opt and D-opt
beta_AD(K = K, nk = nk, alpha = alpha, X = X, y = y)
K |
is the number of subsets |
nk |
is the length of subsets |
alpha |
is the significance level |
X |
is the observation matrix |
y |
is the response vector |
A list containing:
betaA |
The estimator of beta on the A-opt. |
betaD |
The estimator of beta on the D-opt. |
