predict.grpsurvOverlap: Model predictions based on a fitted 'grpsurvOverlap' object.

In YaohuiZeng/grpregOverlap: Penalized Regression Models with Overlapping Grouped Covariates

Description

Similar to other predict methods, this function returns predictions from a fitted "grpsurvOverlap" object.

Usage

## S3 method for class 'grpsurvOverlap'
predict(object, X, type=c("link", "response", "survival",
        "median", "norm", "coefficients", "vars", "nvars", "groups", "ngroups"),
        latent = FALSE, lambda, which=1:length(object$lambda), ...)

Arguments

Adoptted from predict.grpsurv:

object	Fitted "grpsurvOverlap" model object.
X	Matrix of values at which predictions are to be made. Not used for type="coefficients" or for some of the type settings in predict.
latent	Should plot the paths of latent coefficients? Default is TRUE. Note \hat{γ} is used as the label of y axis to represent latent coefficient vector.
lambda	Values of the regularization parameter lambda at which predictions are requested. For values of lambda not in the sequence of fitted models, linear interpolation is used.
which	Indices of the penalty parameter lambda at which predictions are required. By default, all indices are returned. If lambda is specified, this will override which.
type	Type of prediction: "link" returns the linear predictors; "response" gives the risk (i.e., exp(link)); "survival" returns the estimated survival function; "median" estimates median survival times. The other options are all identical to their grpreg counterparts: "coefficients" returns the coefficients; "vars" returns the indices for the nonzero coefficients; "groups" returns the indices for the groups with at least one nonzero coefficient; "nvars" returns the number of nonzero coefficients; "ngroups" returns the number of groups with at least one nonzero coefficient; "norm" returns the L2 norm of the coefficients in each group.
...	Not used.

Details

See predict.grpsurv for more details.
