Summarizing COM-Poisson Model Fit

summary method for class cmp.

# S3 method for cmp
summary(object, ...)

# S3 method for summary.cmp
print(
  x,
  digits = max(3, getOption("digits") - 3),
  signif.stars = getOption("show.signif.stars"),
  ...
)

Arguments

object

an object class 'cmp', obtained from a call to glm.cmp.

...

other arguments passed to or from other methods (currently unused).

x

a result of the default method of summary().

digits

numeric; minimum number of significant digits to be used for most numbers.

signif.stars

logical. If TRUE, ‘significance stars’ are printed for each coefficient.

Value

summary.cmp returns an object of class "summary.cmp", a list containing at least the following components:

call

the component from object.

family

the component from object.

deviance; residual_deviance

the component from object.

df_residual

the component from object.

df_null

the component from object.

null_deviance

the component from object.

deviance_resid

the deviance residuals: see residuals.cmp.

coefficients

the matrix of coefficients, standard errors, z-values and p-values.

df

a 3-vector of the rank of the model and the number of residual degrees of freedom, plus number of coefficients.

Details

print.summary.cmp tries to be smart about formatting the coefficients, standard errors and gives 'significance stars'. The coefficients component of the result gives the estimated coefficients and their estimated standard errors, together with their ratio. This third column is labelled as Z value as the dispersion is fixed for this family. A forth column gives the two-tailed p-value corresponding to Z value based on the asymptotic Normal reference distribution.
