ar1etp: AR(1) + ETP simulation Routine

Description

Simulate a combined AR(1) + ETP signal, plot spectrum and confidence levels

Usage

ar1etp(etpdat=NULL,iter=100,rho=0.9,ARvar=1,sig=90,tbw=2,padfac=5,ftest=F,fmax=0.1,
       speed=0.5,pl=2,output=F,graphfile=0)

Arguments

etpdat

Eccentricity, tilt, precession astronmical series. First column = time, second column = ETP. If not entered, will use default series.

iter

Number of simulations.

rho

AR(1) coefficient.

ARvar

Multiplicative factor for AR1 noise (1= eqivalent to ETP variance).

sig

Demarcate what confidence level (percent) on plots?

tbw

MTM time-bandwidth product.

padfac

Padding factor.

ftest

Include MTM harmonic f-test results? (T or F)

fmax

Maximum frequency for plotting.

speed

Set the amount of time to pause before plotting new graph, in seconds.

pl

Plot log power (1) or linear power (2)?

output

Output modeled time series? (T or F). If selected, only one simulation performed.

graphfile

Output a pdf or jpg image of each plot? 0 = no, 1 = pdf, 2 = jpeg. If yes, there will be no output to screen. Individual graphic files will be produced for each simluation, for assembling into a movie.
