Prediction for a bivRegion object
Description
This function takes a bivRegion object and allow to obtain region limits for a given covariate value if cond=TRUE. If not, it can be applied to a new dataset to evaluate which points will be included inside the standarized region (for instance, if we estimate a reference region with healthy patients results, we can know where non healthy patients will be located).
Usage
## S3 method for class 'bivRegion'
predict(object, tau = 0.95, newdata = NULL, cond = FALSE, ...)
Arguments
object |
A bivRegion object. |
tau |
A number or vector defining the desired coverage(s) of the bivariate reference/probabilistic region. |
newdata |
An optional data frame containing new covariate values, or new observations. |
cond |
A logical argument, if TRUE, a matrix of values defining the conditional reference region limits is given. |
... |
Additional prediction parameters. |
Value
This function returns reference region limits values for a given covariate value (if cond=TRUE), or which observations falls outside the estimated region (if cond=FALSE).
