unifit

Continuous uniform parameter estimates

Syntax

[ahat,bhat] = unifit(data)
[ahat,bhat,ACI,BCI] = unifit(data)
[ahat,bhat,ACI,BCI] = unifit(data,alpha)

Description

[ahat,bhat] = unifit(data)returns the maximum likelihood estimates (MLEs) of the parameters of the uniform distribution given the data indata.

[ahat,bhat,ACI,BCI] = unifit(data)also returns 95% confidence intervals,ACIandBCI, which are matrices with two rows. The first row contains the lower bound of the interval for each column of the matrixdata. The second row contains the upper bound of the interval.

[ahat,bhat,ACI,BCI] = unifit(data,alpha)controls the confidence level by usingalpha. For example, ifalpha=0.01, thenACIandBCIare 99% confidence intervals.

Examples

r = unifrnd(10,12,100,2); [ahat,bhat,aci,bci] = unifit(r) ahat = 10.0154 10.0060 bhat = 11.9989 11.9743 aci = 9.9551 9.9461 10.0154 10.0060 bci = 11.9989 11.9743 12.0592 12.0341
