wblfit

Fits a Weibull distribution to a data sample.

Syntax

[ahat,bhat,aci,bci] = wblfit(x)

Inputs

x
Data sample.
Type: double
Dimension: vector

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.
