RatioPredictableComponents {s2dv}

Calculate ratio of predictable components (RPC)

Description

This function computes the ratio of predictable components (RPC; Eade et al., 2014).

Usage

RatioPredictableComponents(
  exp,
  obs,
  time_dim = "year",
  memb_dim = "member",
  na.rm = FALSE,
  ncores = NULL
)

Arguments

exp

A numerical array with, at least, 'time_dim' and 'memb_dim' dimensions.

obs

A numerical array with the same dimensions than 'exp' except the 'memb_dim' dimension.

time_dim

A character string indicating the name of the time dimension. The default value is 'year'.

memb_dim

A character string indicating the name of the member dimension. The default value is 'member'.

na.rm

A logical value indicating whether to remove NA values during the computation. The default value is FALSE.

ncores

An integer indicating the number of cores to use for parallel computation. The default value is NULL.

Value

An array of the ratio of the predictable components. it has the same dimensions as 'exp' except 'time_dim' and 'memb_dim' dimensions.

Examples

exp <- array(data = runif(600), dim = c(year = 15, member = 10, lat = 2, lon = 2))
obs <- array(data = runif(60), dim = c(year = 15, lat = 2, lon = 2))
RatioPredictableComponents(exp, obs)
