Correlation and regression-errors and pitfalls
Borovcnik, Manfred
Correlation and regression are important tools for empirical research to establish, justify and describe relations between characteristics. The concepts stem from a specific historical background and were intended to imitate causal connections for empirical research in wider areas than physics. While in physics the rank of causality has been changed drastically by entrenching theoretical physics models with genuine -- randomness, the search for causal relations in soft sciences is still an ideal. The methods are applied by scientists from other disciplines than mathematics and statistics who have to interpret them from a "wider perspective". However, misunderstandings and misinterpretations about the concepts involved are also wide-spread even among statisticians. Common errors and pitfalls with regression and correlation are dealt with to enhance the concepts.

The maple program procedures at solution of differantial equations with Taylor collocation method
Servi, Sema; Keskin, Yıldıray
Numerical methods which are based on algorithm and given solutions fastly, are come into prominence for solution of differential equations are encountered in applied mathematics and some of enginering problems, don't have analytical solutions or have so difficult and time-consuming solutions. One of these methods is Taylor Collocation method. To solve complex situations are encountered and to acquire solutions of the other engineering problems are possible with the mentioned method. In this study we show that are given definition of Taylor Collocation Method and calculations of this method, some of differential equations can solve via Maple computer programme.

On the Pell sequence and Hessenberg matrices
Yılmaz, Fatih; Bozkurt, Durmuş
In this paper, we investigate the relationship between permanents of one type of upper-Hessenberg matrices (of odd order) and the Pell numbers. At the final part of this paper, we give a Maple 13 source code to strength our calculations.
