Anderson-Darling Test for Exponentiality
Performs an approximate Anderson-Darling goodness-of-fit test, which verifies the null hypothesis: Data follow an exponential distribution.
exp_test_ad(x)
x |
a non-negative numeric vector of data values |
Sample size should be not less 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. As a result, the resulting p-value distribution might not necessarily be uniform for p>>0.5.
A list of the class htest is returned,
just like in many other testing methods,
see, e.g., ks.test.
