### Expectation of maximum of i.i.d Weibull random variables?

I'm trying to find an asymptotic approximation for the expectation of the maximum of $n$ Weibull random variables $X_i \sim Weibull(\lambda,\beta)$ when $\beta < 1/2$ and $n$ is large. From ...

### How to generate random failure time conditional to a lower bound

For my Monte Carlo simulation (job related) I needed to generate random numbers with conditional probability of related distribution. (example: given that an item has been working for 1200 hours, ...

### Interpreting intercept of parametric AFT survival model (predict.survreg output)

I am trying to work out under what circumstances you would use the 'response' function in the survreg.predict function in r. I have read an excellent response by Tery Therneau, author of the survival ...

### How can I fit a weibull distribution based on the output of its pdf?

I have values which approximate the output of pdf(x) for a distribution over a range of x. I would like to determine the parameters of the two-parameter Weibull distribution which best fits these ...

### Compare two Weibull distributions

I want to compare two Weibull distributions fitted to two different datasets. Both datasets have a distribution that resembles the Weibull so the idea was to compare the fitted Weibull distributions ...

### Problem of the pdf plot for Weibull distribution [duplicate]

I'm using MATLAB to plot the Weibull distribution function. But the y-axis, obviously, is not probability. Also, the plot on Wikipedia (here)has same y-axis as mine, so my question is: is there ...

### Is there any particular converging pattern for Least Square Estimators and Maximum Likelihood Estimators when we increasing the sample size?

My questions is: Is there any particular converging pattern for Least Square Estimators and Maximum Likelihood Estimators of Weibull distribution when we increase the sample size? is there any ...
