unifit

Syntax

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

Inputs

x

Data sample.

Type: double

Dimension: vector

Outputs

ahat

An estimate of the lower bound a.

bhat

An estimate of the upper bound 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.

Example

x = [4.1 4.19 4.43 4.69 4.21 4.72 4.09 4.69 3.85 4.25 4.29 3.77 3.88 3.6 4.78 3.11 4.93 3.55 3.77 3.96];
[a,b,aci,bci] = unifit(x)

a = 3.11
b = 4.93
aci = [Matrix] 2 x 1
2.81589
3.11
bci = [Matrix] 2 x 1
4.93
