Description
This function performs the overall goodness-of-fit test for the Cormack-Jolly-Seber model. It is obtained as the sum of the 4 components Test3.SR, Test3.SM, Test2.CT and Test2.CL.
Usage
overall_CJS(X, freq, rounding = 3)
Arguments
X |
is a matrix of encounter histories |
freq |
is a vector of the number of individuals with the corresponding encounter history |
rounding |
is the level of rounding for outputs; default is 3 |
Value

Examples
# read in the classical dipper dataset
dipper = system.file("extdata", "ed.inp", package = "R2ucare")
dipper = read_inp(dipper,group.df=data.frame(sex=c('Male','Female')))
# Get encounter histories, counts and groups:
dip.hist = dipper$encounter_histories
dip.freq = dipper$sample_size
dip.group = dipper$groups
# split the dataset in males/females
mask = (dip.group == 'Female')
dip.fem.hist = dip.hist[mask,]
dip.fem.freq = dip.freq[mask]
mask = (dip.group == 'Male')
dip.mal.hist = dip.hist[mask,]
dip.mal.freq = dip.freq[mask]
# for females
overall_CJS(dip.fem.hist, dip.fem.freq)
