unitests | R Documentation |
The functions perform F
or t
testing for several responses based
on a matrix of hypothesis observations and a matrix of error observations.

Degrees of freedom for error needs to be specified if
|
modelData
and errorObs
correspond to hypObs
and
errorObs
calculated by xy_Obj
. These matrices are efficient
representations of sums of squares and cross-products (see
xy_Obj
for details). This means the univariate
F
-statistics can be calculated straightforwardly from these input
matrices. Furthermore, in the single-degree-of-freedom case,
t
-statistics with correct sign can be obtained.
unitests
is a wrapper function that calls unitest
for each
term in the xyObj
(see xy_Obj
for details) and collects
the results.
