Apply a simple homogeneity test after Galbraith (2003)

Description

A simple homogeneity test for De estimates

Usage

calc_HomogeneityTest(data, log = TRUE, ...)

Arguments

data	RLum.Results or data.frame (required): for data.frame: two columns with De (data[,1]) and De error (values[,2])
log	logical (with default): perform the homogeneity test with (un-)logged data
...	further arguments (for internal compatibility only).

Details

For details see Galbraith (2003).

Value

Returns a terminal output. In addition an RLum.Results-object is returned containing the following elements:

summary	data.frame summary of all relevant model results.
data	data.frame original input data
args	list used arguments
call	call the function call

The output should be accessed using the function get_RLum

Function version

0.3.0

Examples

## load example data
data(ExampleData.DeValues, envir = environment())

## apply the homogeneity test
calc_HomogeneityTest(ExampleData.DeValues$BT998)

## using the data presented by Galbraith (2003)
df <-
 data.frame(
   x = c(30.1, 53.8, 54.3, 29.0, 47.6, 44.2, 43.1),
   y = c(4.8, 7.1, 6.8, 4.3, 5.2, 5.9, 3.0))
