Updating a nonlinear discriminant function estimated from a mixture of two inverse Weibull distributions

Sultan, K.; Al-Moisheer, A. - In: Statistical Papers 54 (2013) 1, pp. 163-175

In this paper, we investigate the problem of updating a discriminant function on the basis of data of unknown origin …. We consider the updating procedure for the nonlinear discriminant function on the basis of two inverse Weibull … distributions in situations when the additional observations are mixed or classified. Then, we introduce the nonlinear discriminant …

Linear discrimination for three-level multivariate data with a separable additive mean vector and a doubly exchangeable covariance structure

Leiva, Ricardo; Roy, Anuradha - In: Computational Statistics & Data Analysis 56 (2012) 6, pp. 1644-1661

In this article, we study a new linear discriminant function for three-level m-variate observations under the … vector. The new discriminant function is very efficient in discriminating individuals in a small sample scenario. An … form solutions do not exist for these unknown parameters. The new discriminant function is applied to a real data set as …
