HW 2 Solution - ISyE

As some concrete examples, first consider the cost of 192.5 in cell (1,2). This is the cost of ordering in period 1 the total demand for the first two periods, D1+D2. Hence the total cost is the ordering cost plus the inventory holding cost of carrying D2 forward by one period, i.e., 80+0.75*150 = …

FAQ: What is dummy coding?

In this case, the value is equal to 10 which is the mean of group 4. The coefficients of each of the dummy variables is equal to the difference between the mean of the group coded 1 and the mean of the reference group. In our example the mean of group 1 is 2 and the difference of 2-10 is -8, which is the value of the regression coefficient for d1.
