摘要:To test whether a correlation between two variables is genuine or spurious, additional variables and equations must be introduced, and sufficient assumptions must be made to identify the parameters of this wider system. If the two original variables are causably related in the wider system, the correlation is genuine.

摘要:The Poisson process and exponential distribution are described and examples of their occurrence in practice are given. Methods are presented for constructing interval estimates of the parameters of the distributions, for making one-sided tests of hypothesis, and for computing confidence intervals for the ratio and the difference of such parameters. A method is also given for comparing three or more Poisson processes.

摘要:The author shows how these problems are generated naturally as a consequence of the following hypergeneral principles: (1) Different ends require different means and different logical structures. (2) In each area, statistical method must and does evolve, mainly by adding both immediate ends and considerations. (3) While techniques are important in experimental statistics, knowing when to use them and why to use them are more important. (4) In the long run, it does not pay a statistician to foo...
