test_rangeshift: Range shift hypothesis tests
In marcher: Migration and Range Change Estimation in R

Description Usage Arguments Value Functions

Three tests for three hypotheses to test on fitted range shifts: Was the range shift significant? Did an animal that performed two consecutive seasonal migrations return to the same location it began? Was there a stopover during a migration?

test_rangeshift(FIT, verbose = TRUE)

test_return(FIT, verbose = TRUE)

test_stopover(FIT, verbose = TRUE)

`FIT`	a fitted range shift (output of `estimate_shift`)
`verbose`	whether to print verbose message

Outputs a summary of the test results and returns a list of test results including:

aic.table an AIC table comparing models
lrt a likelihood ratio test statistic
df degrees of freedom for the l.r.t.
p.value a p.value for the l.r.t.

test_rangeshift: Compare a two range fitted model to a null model of no range shift.
test_return: Compares a three range fitted model in which the first and third ranges have the same centroid against a model where the first and third centroid are different.
test_stopover: Compare a three range model with an apparent stopover (shorter intermediate range), and see if a more parsimonious model excludes the stopover.
