coef(object, ...)

# S3 method for class 'dgaps'
vcov(object, type = c("observed", "expected"), ...)

# S3 method for class 'dgaps'
nobs(object, ...)

# S3 method for class 'dgaps'
logLik(object, ...)

# S3 method for class 'dgaps'
print(x, digits = max(3L, getOption("digits") - 3L), ...)

# S3 method for class 'dgaps'
summary(
  object,
  se_type = c("observed", "expected"),
  digits = max(3, getOption("digits") - 3L),
  ...
)

# S3 method for class 'summary.dgaps'
print(x, ...)

Arguments

object

and object of class c("dgaps", "exdex") returned from dgaps.

...

For print.summary.dgaps, additional arguments passed to print.default.

type

A character scalar. Should the estimate of the variance be based on the observed information or the expected information?

x

print.dgaps. An object of class c("dgaps", "exdex"), a result of a call to dgaps.

print.summary.dgaps. An object of class "summary.dgaps", a result of a call to summary.dgaps.

digits

print.dgaps. The argument digits to print.default.

summary.dgaps. An integer. Used for number formatting with signif.

se_type

A character scalar. Should the estimate of the standard error be based on the observed information or the expected information?

Value

coef.dgaps. A numeric scalar: the estimate of the extremal index \(\theta\).

vcov.dgaps. A \(1 \times 1\) numeric matrix containing the estimated variance of the estimator.

nobs.dgaps. A numeric scalar: the number of inter-exceedance times used in the fit. If x$inc_cens = TRUE then this includes up to 2 censored observations.

logLik.dgaps. An object of class "logLik": a numeric scalar with value equal to the maximised log-likelihood. The returned object also has attributes nobs, the numbers of \(K\)-gaps that contribute to the log-likelihood and "df", which is equal to the number of total number of parameters estimated (1).

print.dgaps. The argument x, invisibly.

summary.dgaps. Returns a list containing the list element object$call and a numeric matrix summary giving the estimate of the extremal index \(\theta\) and the estimated standard error (Std. Error).

print.summary.dgaps. The argument x, invisibly.

Examples

See the examples in dgaps.
