Remarks on some learning algorithms
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)In this paper we present some problems concerning artificial intelligence. In the first two points there are presented algorithmic and heuristic procedures, which are applied in solving problems and making optimal decision ... -
Remarks on the generalized doubly truncated gamma distribution
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)In the present paper we discuss a doubly truncated generalized gamma distribution and give formulae for the moments of this distribution and special cases together with examples of calculations. -
Switching regression models with non-normal errors
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)In this paper two forms of switching regression models with non-normal errors are considered. The pseudo maximum likelihood method is proposed for the estimation of their parameters. Monte Carlo experiments results are ... -
The distribution and parameters of the distribution of the quotient of random variables
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)This paper presents some important earlier results of the research concerning the properties of the distribution of the quotient of random variables. We present also our own ideas and results of the research concerning ... -
The verification of the multivariate normal distribution hypothesis in a one-sample model with the method of elimination of disturbing parameters
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)In many statistical tasks a necessity of testing multivariate normality arises. In constructing multivariate normality tests there is a necessity of estimating unknown parameters ц and £ from a given sample. The parameters ... -
Usefullness of Durbin method for investigating normality in one-dimensional linear model
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)In this paper the verification of hypotheses of univariate normality by Durbin randomized method is presented. The method of elimination of the nuisance parameters by calculating the residual vector and connected residual ...
