    Construction of dependence function of annual passenger flow and GPD per capita
    (National Aviation University, 2021) Dohonova K. O.; Bortnik Y.V.
    In many problems of physics, economics, medicine, engineering, etc. we have to experimentally study the dependence of a random variable Y, observed, on one or more other random or non-random variables Х_1,Х_2,…,Х_n. Regression analysis is a branch of mathematical statistics that studies the dependence between random variables using regression equations, and regression is the functional dependence on average of any random variables.
