wblfit
Fits a Weibull distribution to a data sample.
Syntax
[ahat,bhat,aci,bci] = wblfit(x)
Inputs
- x
- Data sample.
Outputs
- ahat
- An estimate of the scale parameter a.
- bhat
- An estimate of the shape parameter b.
- aci
- A confidence interval for a. A two-element vector containing the lower and upper bounds of the interval.
- bci
- A confidence interval for b. A two-element vector containing the lower and upper bounds of the interval.
