# Transformation of point estimates

### Description

`transform`

method for class inference

### Usage

1 | ```
transform.inference(`_data`, f, f.prime, ...)
``` |

### Arguments

`_data` |
Object of class |

`f` |
Function to transform the point estimates and confidence intervals; e.g., |

`f.prime` |
Derivative of |

`...` |
Nothing. |

### Details

Transform the point estimates, confidence intervals, and standard
errors based on the delta method. This builds on the S3 generic
function `transform`

from the `base`

package.

It can be used to get the hazard ratio scale in inference objects
created from `coxph`

objects and the odds ratio scale from
logistic regression created from `glm`

(both using `f=exp, f.prime=exp`

).

### Value

Object of class `inference`

.
