findSigRegions {JWileymisc}

Function to find significant regions from an interaction

Description

This function uses the contrast function from rms to find the threshold for significance from interactions.

Usage

findSigRegions(
  object,
  l1,
  l2,
  name.vary,
  lower,
  upper,
  alpha = 0.05,
  starts = 50
)

Arguments

object

A fitted rms object

l1

the first set of values to fix for the contrast function

l2

the second set of values to fix for the contrast function

name.vary

the name of the model parameter to vary values for to find the threshold. Note that this should not be included in l1 or l2 arguments.

lower

The lower bound to search for values for the varying value

upper

The upper bound to search for values for the varying value

alpha

The significance threshold, defaults to .05

starts

Number of starting values to try between the lower and upper bounds.

Value

A data table with notes if no convergence or significance thresholds (if any).
