Anderson–Darling Test
- 587 Downloads
The Anderson–Darling test is a goodness-of-fit test which allows to control the hypothesis that the distribution of a random variable observed in a sample follows a certain theoretical distribution. In particular, it allows us to test whether the empirical distribution obtained corresponds to a normal distribution.
HISTORY
Anderson, Theodore W. and Darling D.A. initially used Anderson–Darling statistics, denoted A2, to test the conformity of a distribution with perfectly specified parameters (1952 and 1954). Later on, in the 1960s and especially the 1970s, some other authors (mostly Stephens) adapted the test to a wider range of distributions where some of the parameters may not be known.
MATHEMATICAL ASPECTS
Let us consider the random variableX, which follows the normal distribution with an expectation μ and a variance \( { \sigma^2 } \)
