R package estimability: Support for determining estimability of linear functions
nonest.basis()function is provided that determines a basis for the null space of a matrix. This may be used in conjunction with
is.estble()to determine the estimability (within a tolerance) of a given linear function of the regression coefficients in a linear model.
- A set of
epredict()methods are provided for
mlmobjects. These work just like
predict(), except an
NAis returned for any cases that are not estimable. This is a useful alternative to the generic warning that "predictions from rank-deficient models are unreliable."
- A function
estble.subspace()that projects a set of linear functions onto an
estimable subspace (possibly of smaller dimension). This can be useful in creating a set of estimable contrasts for joint testing.
