print.bootci {boot} | R Documentation

## Print Bootstrap Confidence Intervals

### Description

This is a method for the function `print()` to print objects of the class `"bootci"`.

### Usage

    ## S3 method for class 'bootci':
    print(x, hinv = NULL, ...)

### Arguments

`x` | The output from a call to `boot.ci`.
`hinv` | A transformation to be made to the interval end-points before they are printed.
`...` | further arguments passed to or from other methods.

### Details

This function prints out the results from `boot.ci` in a "nice" format. It also notes whether the scale of the intervals is the original scale of the input to `boot.ci` or a different scale and whether the calculations were done on a transformed scale. It also looks at the order statistics that were used in calculating the intervals. If the smallest or largest values were used then it prints a message

`Warning : Intervals used Extreme Quantiles`

Such intervals should be considered very unstable and not relied upon for inferences. Even if the extreme values are not used, it is possible that the intervals are unstable if they used quantiles close to the extreme values. The function alerts the user to intervals which use the upper or lower 10 order statistics with the message

`Some intervals may be unstable`

### Value

The object `ci.out` is returned invisibly.
