Produces two-sided Bonferroni and Scheffe simultaneous confidence intervals, together with corresponding single confidence intervals, for any vector of estimable functions A.beta in a linear model.
1 |
y |
Responese vector in linear model. |
X |
Design/model matrix or matrix containing values of explanatory variables (generally including intercept). |
A |
Coefficient matrix (A.beta is the vector for which confidence interval is needed). |
alpha |
Collective non-coverage probability of confidence intervals. |
tol |
A relative tolerance to detect zero singular values while computing generalized inverse, in case X is rank deficient (default = sqrt(.Machine$double.eps)). |
Normal distribution of response (given explanatory variables and/or factors) is assumed.
The three sets of confidence intervals listed as below:
BFCB |
Two-sided Bonferroni simultaneous confidence intervals. |
SFCB |
Two-sided Scheffe simultaneous confidence intervals. |
SNCB |
The single confidence intervals. |
