This example shows the use of the %PDL macro for polynomial distributed lag models. Simulated data is generated so that Y is a linear function of six lags of X, with the lag coefficients following a ...

A polynomial is a chain of algebraic terms with various values of powers. There are some words and phrases to look out for when you're dealing with polynomials: \(6{x^5} - 3{x^2} + 7\) is a polynomial ...

Dividing rational expressions is very similar to multiplying, with one extra step: invert and multiply. This means you flip ...

If the discriminant (b² - 4ac) is negative, the roots are complex numbers. Complex roots always come in conjugate pairs (a + ...

If a polycyclic-by-finite rank-K group Γ admits a faithful affine representation making it acting on R K properly discontinuously and with compact quotient, we say that Γ admits an affine structure.
