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 ...

3. A polynomial of degree one is called a linear polynomial. 4. A polynomial of degree two is called a quadratic polynomial. 5. A polynomial of degree three is called a quadratic polynomial.

to form a polynomial equation. An equation that includes three terms with variables, followed by a quadratic and linear term, is known as a trinomial equation. This type of equation is also ...

Polynomial trending describes a pattern in data that is curved or breaks from a straight linear trend. It often occurs in a large set of data that contains many fluctuations. As more data becomes ...
