calc_HomogeneityTest function

Apply a simple homogeneity test after Galbraith (2003)

A simple homogeneity test for De estimates For details see Galbraith (2003).

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).

Returns

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))

calc_HomogeneityTest(df)
