AMC Datasets

AMC Datasets comprise a growing collection of data likely to be of use to analytical scientists involved in the teaching, learning, or studying of statistical and chemometrics methods and in testing computer software. A dataset could, for instance, be used by a teacher to illustrate a statistical method applied to a particular analytical activity, by a student to try out alternative methods or different statistical packages, or by a research worker to act as an example with known characteristics for the development of new and improved methods.

AMC Datasets are presented as text files, for ease of opening in a wide range of application packages. They have embedded descriptions of the type and source of the data. At present the datasets are simply listed, as below but, as the collection grows, AMC will provide a search facility so that particular types of data can be rapidly identified.

Datasets are described either as ‘Experimental’ or ‘Simulated’. Experimental datasets are as observed by the original author. Simulated datasets represent real situations but have been modified or disguised in some way to preserve the anonymity of the source or other aspects of the data.

These datasets may be freely downloaded and used. Any new results obtained from the study of the datasets may be published freely, but the data themselves must not be republished without the consent of the original author.
