Logistic model

Description

Creates a time series from the logistic model.

Usage

logistic(iter=1000, r=4,x=0.2,t=0,noisesd=0)

Arguments

iter length of the time series.
r parameter of the logistic model.
x initial cohordinate.
t number of transients discarded.
noisesd standard deviaton of white Gaussian noise.

Details

If noisesd is set greater than zero, then the iterated model becomes:

x_[t+1]=rx_[t](1-x_[t])+n,

where n is drawn from N(0,noisesd).

Value

A vector containing the time series.

Examples

## Not run: 

dat <- logistic(150,3.9,0.1,1000)
plot(dat,xlab="Time",ylab="x", main="Time Series from Logistic Model with r=3.9",
type="l")

## End(Not run)
