Quadratic regression. Polynomial swinging.

Mathematically perfect solutions may have statistical flaws. Alas, a textbook published in the United States lacks mathematical statistics. Many actions are detailed, You will master them without a professor! Images of the highest quality! Understanding the inverse matrix is a difficulty that ceases to exist in this book! The area under the curve is calculated step by step. This is promising when calculating the area of a complex land plot. Compiled a program in MATLAB, You protect land rights. The book continues works published in open access journals, indexed in SKOPUS: "Applied and Computational Mathematics" and "Astrophysics and Aerospace Engineering": "Multiple Regression on the Example of the Presidential Elections in the United States during the Period from 1916 to 2000" (8444 readers) And "Power Regression as an Example of the Third Law of Hotels in Paris: Planets" (8567). The first article on November 25, 2016 was awarded a diploma of Moscow Independent University. The author completes the doctoral thesis "Forecast of tax revenues to the budget of Vladivostok".A book for students, for applicants for academic degrees, for forecasting departments and research institutes.
