upper.record.values {Records}

Sample Upper k-Record Values

Description

Produces upper k-record values for a given sample

Usage

upper.record.values(sqnc, k)

Arguments

sqnc

numeric vector of data whose upper k-record values are wanted

k

an integer between 1 and length(sqnc) indicating the rank of upper k-record values

Value

a vector of upper k-record values associated with a given sample

Note

The notion of the k-record value was introduced by Dziubdziela and Kopocinski (1976). k-record value is a generalization of the record value in the meaning of such value which is larger (upper record value) or smaller (lower record value) than all previous observations.

Similarly, the k-record time is the extension of record time, that is the moment in which the record value is observed.

Examples

set.seed(10)
x <- rnorm(100)
upper.record.values(sqnc = x, k = 1) #simply upper record values
upper.record.values(sqnc = x, k = 3)
