1949G. A. Barnard in Jrnl. R. Statistical Soc. B. XI. 116 There are great advantages in working in terms of odds rather than in terms of probabilities—and greater advantages still in working in terms of logarithms of odds... This suggested the adoption of log odds (or, as they are called below, lods) as the fundamental idea in the theory, in place of probabilities. 1955Amer. Jrnl. Human Genetics VII. 292 The scores in a sequential test are ‘lods’, or logarithms of the probability ratio... Tables 4–8 give the possible certain matings and the lod scores appropriate to them. 1974Nature 7 June 595/2 The evidence can be evaluated in the conventional currency used in human linkage studies, the lod, or logarithm of the odds ratio. 1977Lancet 24/31 Dec. 1311/1 The lod-score analysis for genetic linkage between HLA and C.A.H. for families 1, 2, 3, 4, and 5 demonstrated that HLA and the C.A.H. trait are very closely linked. 1988Nature 26 May 308/3 The publication of another paper in Nature which uses ‘Lod scores’ to describe the analysis of human linkage data prompts me to wonder whether it might not be an opportune moment for linkage workers to abandon their idiosyncratic statistical terminology so that others can better follow their analyses. 1990Ann. Human Genetics LIV. 254 An average liklihood is meaningful, an average lod is not. |
