MLE estimation using AS 138 for censored and confined normal.
1 |
y |
observations |
L |
lower bound for each observation that is equal to -Inf when none, default -Inf |
U |
upper bound for each observation that is equal to Inf when none, default Inf |
a list with the following components:
est |
matrix with mean and sd and their se |
covMat |
covariance matrix |
nobs |
number of complete observations |
itercount |
number of iterations |
ifault |
fault indicator. 0-converged. -1:convergence not obtained in default number of allowed iterations. -2:fewer than 2 complete obserations. -3:error with confined estimator initial values (should not occur in R version). -4:invalid specification for limits with confined observation. |
