Arguments
a
ar-coefficients
b
ma-coefficients
nf
scalar, the number of equally spaced frequencies
s
variance of error process
pl
logical, if TRUE, the spectrum is plotted, FALSE for no plot
Value
out (nf+1,2) matrix, the frequencies and the spectrum
Examples
1
out <-armathspec(c(0.3,-0.5),c(-0.8,0.7),50,s=1,pl=FALSE)
