Standard error of Weibull MLE estimates

5 views (last 30 days)
Hello, The built-in [p,ci]=wblfit(data) command gives the parameter estimates and their 95% confidence intervals of a Weibull distribution. Is there an easy wa to get the standard errors of the estimates instead of the confidence intervals?

The standard error is basically 1/4 of the length of the confidence interval.

Because a 95% confidence interval is the observed value plus or minus 1.96*std_err, where +/-1.96 are the 95% cutoffs for the normal distribution.
