Re: [R] Exponential distribution

The code is like this: plot(0,0, type="n", xlim=c(1,15), ylim=0:1, xlab="...", ylab="...", main="Example) lines(1:15, line1, col=4) lines(1:15, line2, col=2) legend("topright", c("alpha = 0.2", "alpha = 0.4"), col=c(4,2), lty=1) How can I build the vectors line1 and line2 ? -- View this messag

[R] Exponential distribution

Dear R-users, I have to plot a exponential distribution like the plot in the pdf attached. I've write this code but I don't know how to draw the two lines.. Can anyone help me please? Thank you very much Pippo http://r.789695.n4.nabble.com/file/n3394476/exponential_smoothing.pdf exponentia

Re: [R] exponential distribution

What do you mean by 'correct' here? If you do manually what glm() does, you would expect to get the same answer, but that is not independent verification. As far as I recall either glm nor survreg are calculation the exact variance in this case -- they are both making use of asymptotic theory

[R] exponential distribution

Dear all, I've tried to solve the Es. 12, cap 4 of "Introduction to GLM" by Annette Dobson. It's about the relationship between survival time of leukemia patients and blood cell count. I tried to fit a model with exponential distribution, first by glm (family gamma and then dispersion paramete
