Re: [R] noisy quantisation; Bernoulli scheme
If I am right, the original version was a sinusoidally-modulated (nonstationary) Bernoulli process. I want 3 possible values, not 2, which makes it a "Bernoulli scheme" http://en.wikipedia.org/wiki/Bernoulli_scheme Not sure how to the create a sinusoidally modulated Bernoulli scheme with values 0, 0.5, 1.

Re: [R] noisy quantisation
If this helps, here is what I have currently mean.p<- .5 contrast<-1 amp<- contrast*mean.p freq<- 3 n<- 100 p<-amp*cos(2*pi*freq*(1:n)/n ) + mean.p plot(p) dens<-as.numeric(runif(1:n)https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] noisy quantisation
The following creates a point process version of a sinewave (maybe there's a better way): p<-amp*cos(2*pi*freq*(1:n)/n ) + 0.5 as.numeric(runif(1:n)https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
