Proper handling of continuous variables is crucial in healthcare research, for example, within regression modelling for descriptive, explanatory, or predictive purposes. However, inadequate methods ...

Abstract: For pt.2 see ibid., vol. 26, no. 4, p. 90-100 (2006). Our ultimate goal here is twofold. We want to get insight into how cubic polynomials work, what are the invariants/covariants and their ...

Polynomials and power functions are the foundation for modelling non-linear relationships. Polynomial functions such as quadratic, cubic and quartic model variables raised to exponents of different ...

Polynomial equations are fundamental concepts in mathematics that define relationships between numbers and variables in a structured manner. In mathematics, various equations are composed using ...

A cubic equation is an algebraic expression that involves the variable of the highest degree as a cube. It has the general form ax^3 + bx^2 + cx + d = 0, where a, b, c, and d are constants and x ...

ABSTRACT: We will use a simple method to generate integer sequences whose terms are sums of mixed powers of trigonometric values at angles of a heptagonal triangle. Our results include many new ...

Abstract: The model of local sources captures sources of randomness which are generated by simple processes where each output bit is a function of a small number of uniformly random input bits.
