Get Model Response Variable
Extract the response variable from a fitted model on the original or link scale.
getY(mod, data = NULL, link = FALSE, offset = FALSE, env = parent.frame())
mod |
A fitted model object, or a list or nested list of such objects. |
data |
An optional dataset, used to first refit the model(s). |
link |
Logical. If |
offset |
Logical. If |
env |
Environment in which to look for model data (if none supplied). |
getY will return the response variable from a model by
summing the fitted values and the response residuals. If link = TRUE
and the model is a GLM, the response is transformed to the link scale. If
this results in undefined values, an estimate based on the 'working'
response variable of the GLM is returned instead (see
glt).
Any offset variables are subtracted from the response by default. This means that, for example, rates rather than raw counts will be returned for poisson GLMs (where applicable).
A numeric vector comprising the response variable on the original or link scale, or an array, list of vectors/arrays, or nested list.
# All SEM responses (original scale) getY(Shipley.SEM) # Estimated response in link scale from binomial model getY(Shipley.SEM$Live, link = TRUE)
