Variations in phosphate concentrations with depth and the effects of variability in the capacity of soils to fix phosphate can cause spurious patterns in phosphate surveys. Using the results from three contrasted sites in Wales, this paper illustrates the nature and magnitude of the problems that ca

## Abstract Here we present a method that permits one to evaluate genetic effects and to detect genetic linkages by using serial observations of quantitative traits in pedigrees. We developed a statistical method that incorporates longitudinal family data and genetic marker information into an esti
Principal component analysis is a useful method for analysing data-matrices. By analysing separate class models, i.e. disjoint principal component modelling as in the SIMCA or FCVPC programs (developed for supervised and unsupervised principal component analysis respectively), the principal componen
The observed mortality of a group of individuals often needs t o be compared with that expected from the death rates of the national population, with allowance made for period, age, 8ex and race. This is achieved by the person-years or subject-years method. A different approech is propod which leads
