A-bstract. Piecewise polynomials or splines extend the advantages of polynomials to include greater flexibility, local effects of parameter changes and the possibility of imposing useful constraints… Expand

A new method that uses noisy measurements on a subset of variables to estimate the parameters defining a system of non‐linear differential equations, based on a modification of data smoothing methods along with a generalization of profiled estimation is described.Expand

Book of functional data analysis springer series in statistics, as an amazing reference becomes what you need to get, and book, as a source that may involve the facts, opinion, literature, religion, and many others are the great friends to join with.Expand

The option characteristic curve, the relation between ability and probability of choosing a particular option for a test item, can be estimated by nonparametric smoothing techniques. What is smoothed… Expand

Most statistical analyses involve one or more observations taken on each of a number of individuals in a sample, with the aim of making inferences about the general population from which the sample… Expand

Multivariate data analysis permits the study of observations which are finite sets of numbers, but modern data collection situations can involve data, or the processes giving rise to them, which are… Expand

Scientists often collect samples of curves and other functional observations, and develop models where parameters are also functions. This volume in the UseR! Series is aimed at a wide range of… Expand
