previous_equal: Relative Frequency of Previous Equal Elements

In JuGross/ensAR: Autoregressive postprocessing methods for ensemble forecasts

Description

Compares each feasible element of a vector to a given number of previous elements and computes the relative frequency of successes, where a success occurs in case of positive equality comparison.

Usage

previous_equal(x, previous = 10)

Arguments

x	A numeric vector.
previous	The number of previous elements compared to the actual element.

Details

For each element of x greater than previous, a success is recorded when it is equal to the last previous elements, where equality is assessed by all.equal.

Value

Relative frequency of possible successes as decribed in the Details section.

Examples

x <- c(1, 1, 2, 1, 2, 2, 2, 3)
previous_equal(x, previous = 1) # 3/7
previous_equal(x, previous = 2) # 1/6
