rangeCheck {cNORM} | R Documentation

## Check for horizontal and vertical extrapolation

### Description

Regression model only work in a specific range and extrapolation horizontally (outside the original range) or vertically (extreme norm scores) might lead to inconsistent results. The function generates a message, indicating extrapolation and the range of the original data.

### Usage

    rangeCheck(
      object,
      minAge = NULL,
      maxAge = NULL,
      minNorm = NULL,
      maxNorm = NULL,
      digits = 3,
      ...
    )

### Arguments

`object` | The regression model or a cnorm object
`minAge` | The lower age bound
`maxAge` | The upper age bound
`minNorm` | The lower norm value bound
`maxNorm` | The upper norm value bound
`digits` | The precision for rounding the norm and age data
`...` | additional parameters

### Value

the report
