simCoreArray: Simulate a proxy core array

In EarthSystemDiagnostics/proxysnr: Separate Signal and Noise in Climate Proxy Records

Simulate a proxy core array

Description

Simulate an array of proxy records with each record being composed of a signal that is common to all the records in the array and an independent noise component. Both components are simulated such that their spectra follow a power-law of the form 'alpha * f^(-beta)' where 'f' denotes frequency.

Usage

simCoreArray(signal.par, noise.par, nc, nt)

Arguments

signal.par	a named list with elements 'alpha' and 'beta' supplying the power-law parameters to simulate the common signal.
noise.par	as signal.par the power-law parameters to simulate the independent noise components.
nc	the number of proxy records ('"cores"') in the array.
nt	the length of each record in the array.

Value

a list with 'nc' elements where each is one simulated proxy record of length 'nt'.
