Спереводом : 3 time-series analysis shows how variables change over a period of time. how salaries increased over the last century, for example. cross-sectional analysis compares variables at one point in time. the salaries of men compared to women right now, for example. of course, economists like to make things more complicated than that. sometimes they combine cross-sectional with time-series analysis, and this is called panel data analysis. as we said earlier, econometrics is good for testing economic theories. however, there is also a practical side to econometrics. the same maths and statistics are used by governments and business managers, as well as academics. econometrics can help governments and companies find out how well they are doing. with the data from all this mathematics, they can make better decisions and plan better for the future.
