Code
This is the code used to generate the plot. It could have been done more efficiently, but this way is more self-explanatory.
SpacingEstimate<-function (x) { A1<-1-exp(-2*x) A2<-1-exp(-4*x) Z<-(A1)*(A2-A1)*(1-A2) return(log(Z)) } Likelihood<-function (x) { A1<-x*exp(-2*x) A2<-x*exp(-4*x) Z<-A1*A2 return(log(Z)) } x<-seq(0,1,.01) plot(x,SpacingEstimate(x),main="Comparison of Estimator Values", type="l", col="blue", xaxp=c(0,1,10), lwd=2, ylab="Estimator values") points(x, Likelihood(x), col="dark green", type="l", lwd=2) arrows(.4, -7, .26, -8.1) arrows(.56, -7.45, .33, -8.09) text (x=.463, y = -6.7, labels = "Maximum Spacing Estimate:",col="red") text (x=.45, y = -7.0, labels=expression(frac(ln(.6),-2)),col="red") text (x=.6, y = -7.3, labels = "Maximum Likelihood Estimate:", col="purple") text (x=.6, y = -7.6, labels=expression(frac(1,3)), col="purple") abline(v=(log(.6)/-2), col="red") abline(v=(1/3), col="purple") legend ("topright", legend=c("Maximum Spacing", "Maximum Likelihood"), col = c("blue", "dark green"), lwd=2)
