In this type of analysis, a time series is modeled to determine its components in terms of seasonal patterns, trends, relation to external factors etc. these can then be used for decision making and policy formulation. 1. predictive modeling 2. descriptive modeling 3. time series forecasting 4 all of the above

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)
