    Robust MWCD (minimum weighted covariance determinant) estimator for multivariate data

  • Original language description

    The minimum weighted covariance determinant (MWCD) estimator is a (possibly) highly robust estimator of parameters (expectation and covariance matrix) of multivariate data. Theoretical results of the MWCD are known to be appealing for practical applications, but still the estimator remains to be very little known in the community of applied statisticians. The presented software is the first publicly available implementation of the MWCD estimator. It is based on an approximate algorithm, which is a natural extension of the (very well known and reliable) FAST-MCD estimator of Rousseuw and van Driessen (1999).

  • Technical parameters

    Kód v Matlabu, spustitelný samostatně podle dokumentace, která je součástí jednotlivých souborů. Spuštění vyžaduje knihovnu fastmcd.m. Dostupné pod licencí MIT.

  • Economical parameters

    Jde o dosud první veřejně dostupnou implementaci kódu pro výpočet MWCD odhadu. Software tak výrazně usnadňuje analýzu mnohorozměrných dat pomocí nástrojů robustních vůči odlehlým hodnotám.
