ageTests-class: Class "ageTests"

Description

Results of \(\chi^2\)-tests testing to which number of populations the ages calculated by the function calculateAges() are the most likely to come from. The test is the one described in the article Montel et al. (1996).

Fields

nb.pop

Object of class "vector" that contains the tested numbers of populations.

best.nb

Object of class "numeric" that contains the most probable number of populations, which is the smallest number for which the \(\chi^2\)-test is accepted.

best.res

Object of class "oneAgeTest" that contains the result of the test for best.nb populations.

Objects from the Class

Objects from this class are created by the function tests() applied to an object of class ages when the option nbmax is not set to NULL but to an integer larger than nbmin.

Methods

• print(signature(x = "ageTests")): displays a summary of the test's results.

• show(signature(object = "ageTests")): displays a summary of the test's results.

• summary(signature(object = "ageTests")): displays a summary of the test's results.
