| Parameter | Description |
|---|---|
| x | positive finite real nonempty vector or matrix: sample data. |
| alpha | scalar in the range [0, 1]: significance level. Default is 0.05. |
| censoring | array containing 0 or 1 values: right-censoring flags. |
| freq | array of nonnegative finite values: observation frequencies. |
| options | scalar structure: fitting options. MaxIter and TolX are used when supplied. |
| Parameter | Description |
|---|---|
| phat | array: estimates for mu and sigma parameters. |
| pci | array: confidence intervals for the estimates. |
lognfit estimates the parameters of the lognormal distribution.
