rangeCheck: Check for horizontal and vertical extrapolation

In cNORM: Continuous Norming

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
