On the effective radius of convergence for a given truncated power series expansion
Demetris T. Christopoulos
An effective radius of convergence is defined and computed for any truncated Taylor series. Applications to well known series are performed and is shown that a range of good coinci…

Polynomial regression using trapezoidal rule for computing Legendre coefficients
Demetris T. Christopoulos
We are presenting a method for computing the Fourier coefficients of a given polynomial regression by using the trapezoidal rule for numerical integration. As function basis we use…

Linear Regression without computing pseudo-inverse matrix
Demetris T. Christopoulos
We are presenting a method of linear regression based on Gram-Schmidt orthogonal projection that does not compute a pseudo-inverse matrix. This is useful when we want to make sever…
