## Anderson-Darling Test for Exponentiality

### Description

Performs an approximate Anderson-Darling goodness-of-fit test, which verifies the null hypothesis: Data follow an exponential distribution.

### Usage

exp_test_ad(x)

### Arguments

`x` |
a non-negative numeric vector of data values |

### Details

Sample size should not be smaller than 3. Missing values
are removed from `x`

before applying the procedure.

The p-value is approximate: its distribution has been estimated by taking 2500000 MC samples. For performance and space reasons, the estimated distribution is recreated by a spline interpolation on a fixed number of points. In result, the resulting p-value distribution may not necessarily be uniform for p>>0.5.

### Value

A list of the class `htest`

is returned,
just like in many other testing methods,
see e.g. `ks.test`

.
