predict.tune_xrnet | R Documentation |
Extract coefficients or predict response in new data using
fitted model from a tune_xrnet
object. Note that we currently
only support returning results that are in the original path(s).
## S3 method for class 'tune_xrnet'
predict(
object,
newdata = NULL,
newdata_fixed = NULL,
p = "opt",
pext = "opt",
type = c("response", "link", "coefficients"),
...
)
object |
A |
newdata |
matrix with new values for penalized variables |
newdata_fixed |
matrix with new values for unpenalized variables |
p |
vector of penalty values to apply to predictor variables. Default is optimal value in tune_xrnet object. |
pext |
vector of penalty values to apply to external data variables. Default is optimal value in tune_xrnet object. |
type |
type of prediction to make using the xrnet model, options include:
|
... |
pass other arguments to xrnet function (if needed) |
The object returned is based on the value of type as follows:
response: An array with the response predictions based on the data for each penalty combination
link: An array with linear predictions based on the data for each penalty combination
coefficients: A list with the coefficient estimates for each
penalty combination. See coef.xrnet
.
data(GaussianExample)
## 5-fold cross validation
cv_xrnet <- tune_xrnet(
x = x_linear,
y = y_linear,
external = ext_linear,
family = "gaussian",
control = xrnet_control(tolerance = 1e-6)
)
## Get coefficients and predictions at optimal penalty combination
coef_xrnet <- predict(cv_xrnet, type = "coefficients")
pred_xrnet <- predict(cv_xrnet, newdata = x_linear, type = "response")
