Re: [R] density plot of simulated exponential distributed data

I tried logspline function using a lower bound 0 for my data, it works like a charm. When the I changed the xlim only positive part, the vertical line was also gone. That's exactly what I expected. Thanks. -JJ Greg Snow wrote: You might want to use the logspline package instead of the density

Re: [R] density plot of simulated exponential distributed data

Hi: Try this (and note the use of vectorization rather than a loop): rate <- 3 dta <- -log(1 - runif(1000))/rate hist(dta, nclass = 30, probability = TRUE) x <- c(0.001, seq(0, 3, by = 0.01)) lines(x, dexp(x, rate = 3)) This is the difference in timings between the vectorized and iterative metho

[R] density plot of simulated exponential distributed data

Hi all, I tried to plot the density curve using the data from simulation. I am sure that the data should be exponentially distributed, but the plot of density curve always starts from (0,0) which is not the case for exponential distribution. Is there any way around this, to keep the curve
