Statistical inference

A statistical method of drawing conclusions on unknown properties of a population based on a random sampling of data from that population.

statistical inference

a process by which we infer conclusions about a statistical POPULATION from which only a SAMPLE has been drawn. For example, if one million Britons buy bicycles each year, and 200 are asked why they do so, 50% may say because it helps to keep them fit. From this sample one may infer that 50% of the total population of one million Britons buying bicycles do so for this reason. However, it is not possible to say with 100% accuracy that this is the case unless the views of all one million were obtained. Nevertheless, it is possible to say with reasonable confidence that the estimation of 50% is correct for the whole population.

Introduction to the theory of statistical inference.
The authors introduce order statistics and applications, then cover basic distribution theory, including joint distribution of two order statistics, discrete order statistics, including joint probability mass functions and distributions of the range, order statistics from specific distributions, including Bernoulli and Poisson distributions moment relations, bounds, approximations, characterizations using order statistics, order statistics in statistical inference, asymptotic theory, including central and intermediate order statistics and record values.
The topics are compositional data and their sample space, the Aitchison geometry, coordinate representation, exploratory data analysis, random compositions, statistical inference, linear models, and compositional processes.
They treat all variables--manifest and latent, continuous or categorical--as random variables, then subsequent analysis is done wholly within the realm of the probability calculus and the theory of statistical inference. Previous editions were published in 1987 and 1999; this edition accounts for the significant changes in statistics since them, primarily the increase in computing power, which makes some approaches practical that were not before.
