cluster analysis in one-dimensional circular space

2000-04-14 Thread Carl Frelicot
Hi everybody. I face the problem of clustering one-dimensional data that can range in a circular way. Does anybody knows the best way to solve this problem with no aid of an additional variable ? Using a well-suitable trigonometric transform ? Using an ad-hoc metric ? Thanks. Carl

If your data can be "cut" and unrolled at a specific boundry then you can rotate/translate the data away from the boundry. For example if your data crosses the 0 degree boundry but not the -180/+180 boundry then you don't need to do anything, if it crosses the -180/+180 boundry but not the 0

The normal distribution has often been called the Gaussian distribution, although de Moivre and Laplace spoke of it well before Gauss. The term "normal" had been used for the distribution by Galton (1877) and Karl Person later recommended the routine use of that adjective to avoid "an

Double mass analysis

2000-04-14 Thread Jack Lewis
Can anyone comment on the use of double mass analysis, a commonly recommended technigue in hydrology texts use to detect a change in the assumed linear relation between two variables? The method involves plotting the cumulative values (in time order) of the two variables against one another and
