I need to generate a data set based on this equation X(t) = 3.8x(t-1) (1-x(t-1)) + e(t), where e(t) is a N(0,0,001) random variable I need say 100 values.
How do I do this?
I assume X(t) and x(t) are the same (?).
f<-function (x) { 3.8*x*(1-x) + rnorm(1,0,.001) }
v=c()
x=.1 # starting point
for (i in 1:100) { x=f(x); v=append(v,x) }There may be smarter ways...
