This is the second of a two course sequence in statistical modeling that covers widely applicable (both actuarial and non-actuarial) methods in probability and statistics. These courses are designed to lay the mathematical foundations for students preparing for advances professional actuarial exams. They also serve to provide an introduction to mathematical modeling techniques useful for a wider audience of quantitatively oriented students in business and finance, and science and engineering. Topics in AS411 include the evaluation of data for estimation and goodness-of-fit to models, simple and multiple regression models, time series, forecasting and data credibility models.
