A new statistical test has been developed to detect patterns in data more effectively than existing tests. This test is especially good at finding differences in small sets of data or when changes occur in a small part of the data. The test uses the spacings between data points to identify these patterns. By using this test, researchers were able to improve their ability to find small changes in data, like in searching for bumps or detecting supernovae. The test was shown to perform better than other commonly used tests in certain situations.
