A Robust Distance Coefficient between Distribution Areas Incorporating Geographic Distances

The Distribution of Robust Distances

Mahalanobis-type distances in which the shape matrix is derived from a consistent, high-breakdown robust multivariate location and scale estimator have an asymptotic chisquared distribution as is the case with those derived from the ordinary covariance matrix. For example, Rousseeuw’s minimum covariance determinant (MCD) is a robust estimator with a high breakdown. However, even in quite large ...

Lexical and orthographic distances between Germanic, Romance and Slavic languages and their relationship to geographic distance

When reading texts of different but closely related languages, intelligibility is determined among others by the number of words which are cognates of words in the reader’s language, and orthographic differences. Orthographic differences partly reflect pronunciation differences and therefore are partly a linguistic level. Dialectometric studies in particular showed that different linguistic lev...

Distance Estimation between Transceivers over Short Distances

Three methods for determining distances between a user and a fixed coordinate system are considered. One system is based on 802.11g packet communications, another on HF radio carrier frequency interference, and the final system on a signal transmitted over a radio channel. Emphasis is placed on the use of these systems in indoor, building-sized environments. Tests are performed to examine the e...

Determination of a Distribution Coefficient

Environmental chemistry is a new field of study in many chemistry departments and only three published summaries of environmental laboratory experiments are available (1–3). While these laboratory manuals contain excellent experiments for the training of students in environmental monitoring, relatively few standardized procedures have been published for broader issues such as the measuring of f...
