predict.icenReg_fit function

Predictions from icenReg Regression Model

Gets various estimates from an ic_np, ic_sp or ic_par object.

## S3 method for class 'icenReg_fit'
predict(object, type = "response", newdata = NULL, ...)

Arguments

• object: Model fit with ic_par or ic_sp
• type: type of prediction. Options include "lp", "response"
• newdata: data.frame containing covariates
• ...: other arguments (will be ignored)

Details

If newdata is left blank, will provide estimates for original data set.

For the argument type, there are two options. "lp" provides the linear predictor for each subject (i.e. in a proportional hazards model, this is the log-hazards ratio, in proportional odds, the log proporitonal odds), "response" provides the median response value for each subject, conditional on that subject's covariates, but ignoring their actual response interval. Use imputeCens to impute the censored values.

Examples

simdata <- simIC_weib(n = 500, b1 = .3, b2 = -.3,
                      inspections = 6,
                      inspectLength = 1)

fit <- ic_par(cbind(l, u) ~ x1 + x2,
              data = simdata)

imputedValues <- predict(fit)
