oneAgeTest-class: Class '"oneAgeTest"'

In NiLeDAM: Monazite Datation for the NiLeDAM team

Description

Results of a chi2-test testing if the ages calculated by the function calculateAges come from a given number of populations. The test is the one describes in the article Montel et al. (1996).

Objects from the Class

Object from this class are created by the function tests applied to an object of class ages when the option nbmax is set to NULL.

Slots

data:

Object of class "ages" as created by the function calculateAges. This is the object passed as an argument to the function tests.

ages:

Object of class "vector" that contains the estimated common age(s) of the population(s). Its size is equal to the argument nbmin passed to the function tests.

sd:

Object of class "vector" that contains the estimated standard deviations of the common age(s) of the population(s). Its size is equal to the argument nbmin passed to the function tests.

ic:

Object of class "matrix" having nbmin rows and two columns corresponding to the confidence intervals at level level as passed as an argument to the function tests.

S:

Object of class "numeric" chi2 test statistic of the test.

thres:

Object of class "numeric" probability threshold of the test.

df:

Object of class "numeric" degree of freedom of the test.

level:

Object of class "numeric" confidence level of the test. Passed as an argument to the function tests.

h0:

Object of class "logical" result of the test: if h0 is TRUE, the test is accepted at level level and if h0 is FALSE, the test is rejected at level level.

which.pop:

Object of class "vector" the contains the population number for each analytical point. 1 corresponds to the population with the first age in ages, 2 to the population with the second age in ages...

Methods

print

signature(x = "oneAgeTest"): displays a summary of the results of the test.

show

signature(object = "oneAgeTest"): displays a summary of the results of the test.

summary

signature(object = "oneAgeTest"): displays a summary of the results of the test.
