Warunki zaliczenia

A student performs a report (laboratory) in which selects and solves a forecasting problem using time series models. The positive mark from laboratory is possible if the mark from report is positive. A student not attending to laboratory is not classified. Two tests (class) with mathematical tasks. The person not attending to class is not classified. One test (lecture) multiple choice.

Final mark O is a weighted average of marks from laboratory OL, from class OC and lecture OW, and is determined by the formula: O=0.4*OL+0.4*OC+0.2*OW.
