In this paper we focus on the impact of responses of contaminated normal distribution on the relative potency. For several values of the contamination parameters, the estimates of the relative potency, its goodness and ...

The aim of the papers is to present and discuss the most direct issues on relation between logical many-valuedness and logical probability i.e. probability related to propositions. Having introduced the reader into the ...

In the paper a new definition of the average return rate for a group of investment (or pension) funds is proposed. The definition is derived via integration of the financial results of the group of funds during a given ...

Successive observations over time are made on individual subjects classified into different groups. It is assumed that the mean response may vary between groups, that there is a random effect for each individual, and ...

The bootstraps methods can be widely applied in statistical research. In the paper the bootstraps OLS-estimators for linear models are considered. The results of simulation experiments for linear models with errors which ...

The problem of minimax estimation in the linear regression model is considered under the assumption that a prior information about the regression parameter and the covariance matrix of random component (error) is available ...

Optimal classification rules based on linear functions which maximize the area under the relative operating characteristic curve or which maximize the chosen probabilistic distance between two populations are studied ...

The distribution function of the homogeneous generalized quadratic form is represented as an infinite linear combination of the central Wishart distribution functions. The Probability content of the ellipsoid is expressed ...

The Analytic Hierarchy Process (AHP) is a multicriteria decision support method created by Thomas L. Saaty. It provides both individual and group decision makers an objective way for reaching an optimal decision. The AHP ...
