Reduces a general hypothesis in a linear model into a pair of completely testable and completely untestable hypotheses.
1 |
X |
Design/model matrix or matrix containing values of explanatory variables (generally including intercept). |
A |
Coefficient matrix (A.beta = xi is the null hypothesis to be split). |
xi |
A vector (A.beta = xi is the null hypothesis to be tested). |
tol |
A relative tolerance to detect zero singular values while computing generalized inverse, in case X is rank deficient (default = sqrt(.Machine$double.eps)). |
A list of two objects:
testable |
Coefficient matrix and constant vector for testable part of hypotheses. |
untestable |
Coefficient matrix and constant vector for untestable part of hypotheses. |
