trcoef {emdbook} | R Documentation |
Perform standard transformations of coefficients
based on information encoded in the names or
the transf
attribute of the vector or list
trcoef(x, inverse = FALSE)
x |
A numeric vector of coefficients with names and/or
a transf attribute |
inverse |
(logical) Perform inverse transform? |
If inverse=FALSE
and coefficient names begin with "logit", "log", or "sqrt"
the function will back-transform them (using plogis
,
exp
, or squaring), strip the descriptor
from the names, and set the transf
attribute.
Naturally, inverse=TRUE
will do the opposite.
If the transf
attribute is all empty strings
after an inverse transformation, it will be deleted.
A vector of transformed variables with modified names
and transf
attributes.
