摘要:

The analysis of variance can be represented in terms of the squared simple correlation between each individual's score and his or her group mean. Several insights and advantages emanate from this approach.

摘要:

Various estimators of slope, intercept, and mean response in the simple linear regression problem are compared in terms of unbiasedness, efficiency, breakdown, and mean squared error. Theil's estimator of slope and two intercept estimators based on Theil's estimator are recommended for inclusion in nonparametrics courses as robust, efficient, and easy-to-calculate alternatives to least squares.

摘要:

Even though ancillary statistics contain no information about the unknown parameter, an exhaustive treatment of the data is possible by using them. Here, some simple linear estimators using ancillary statistics are suggested for the parameter in the problem of the Nile.

摘要:

If random variables in one set are defined as explicit functions of random variables in a second set, Taylor series expansion (the delta method) may be used to prove the asymptotic normality of the first set of variates, under appropriate conditions, and to develop needed covariance estimates. Similar results are obtained for a set of random variables that are defined implicitly as functions of a second set of variables. This approach is used to calculate the variance of the attributable risk from case-control data.

摘要:

A continuous-time renewal process (N(t),t≥ 0) is a Poisson process if and only if the conditional distribution of an interarrival time givenN(t) =nis the same as that of the minimum order statistic corresponding tonindependent random variables identically and uniformly distributed on the interval [0,t). Similar characterization is also given for a nonhomogeneous Poisson process.

摘要:

Paul Samuelson and other authors have shown that no element in a population ofnitems can lie farther than (n— 1)½standard deviations from the mean. Other researchers extended this by giving upper and lower bounds for thekth largest item in terms of the population mean and standard deviation. We provide an alternate proof of these results. The technique used in the proof gives insight into the conditions under which the bounds are attained and can be used to improve bounds when additional information is available.

摘要:

Using only a first-year calculus background, a closed-form expression for an orthant probability is derived. The result and examples are appropriate for students in their first course in the theory of nonparametric statistics.

摘要:

An increasing number of statistical software packages offer exploratory data displays and summaries. For one of these, the graphical technique known as the boxplot, a selective survey of popular software packages revealed several definitions. These alternative constructions arise from different choices in computing quartiles and the fences that determine whether an observation is “outside” and thus plotted individually. We examine these alternatives and their consequences, discuss related background for boxplots (such as the probability that a sample contains one or more outside observations and the average proportion of outside observations in a sample), and offer recommendations that lead to a single standard form of the boxplot.
