Extending the Cochran rule

We first describe a number of inter-related issues that need to be considered by the researcher when comparing frequencies of linguistic features in two or more corpora. We then describe the chi-squared and log-likelihood tests used in previous research for the comparison of word frequencies. Our focus, in this paper, is on the issue of reliability of the statistical tests, and we describe simu...

which restricts to the given links at the ends. A link is called (topologically) slice if it is concordant to the trivial m–component link or, equivalently, if it bounds a flat embedding of m disjoint slice disks D2 ∐ · · · ∐D2 ֒→ D4. In the special case m = 1 we refer to the link as a knot. If the embeddings above are required to be C, or smooth, then these notions are called smoothly concordan...

And Donald

In 1983, Popper and Miller published in Nature a new argument against inductive probability. There followed, the next year, a discussion of the validity of the argument in the pages of the same journal involving Good, Jeffrey, and Levi as well as Popper and Miller themselves. This has led in turn to still further discussions of the argument. Those who are critical include Redhead (1985) and Dun...
