    How can I find an interval estimate for the mean of a Weibull distribution?

    I have a sample of n = 75 taken from a Weibull distribution and have computed mle estimates for the scale a and shape b parameter. The mean of a Weibull distribution (2 parameter) is given as u = a^(-1/b)*gamma(1+ 1/b) In which case I can find an estimate for u by simply plugging in the mle...

    Why not use Kaplan Meier?

    In the method described here http://dmkd.cs.vt.edu/papers/TKDE17.pdf R code implementation is provided https://github.com/MLSurvival/ESP/blob/master/ESP_TKDE2016/TKDE_code.R the Kaplan-Meier estimator is initially estimated from data but then (from line 244) different distributions...

    Monte Carlo Simulation , a simpler version

    Hi all, I have asked this question before, but it seems I was not asked it in an appropriate way, so I draw the following flowchart which I think explain the problem much simpler and faster. I have the following situation and would like to do a Monte Carlo Simulation for this. Could you...

    Monte Carlo for Weibull and Lognornam distributions in R

    I am involved in a project which needs statistic and computer science. I am more of a computer guy so I appreciate any statistical help. I am doing most of the process in R. Step A: In the project, I have some sensors which count the number of passing objects in minutes and these sensors...

    Weibull/Normal Distribution Hazard Rate Calculation

    Hi, so I've been searching the web a while for a real example or procedure to get hazard rates from actual data but all I can come up with are theories/derivations, which have not been helpful. I'm trying to do the basic calculations of hazard rates at different points in time from a sample set...
