Indianhead Mountain The area is best known for downhill alpine skiing. Indianhead itself only offers downhill alpine skiing. Indianhead features runs from very easy greens through double diamond. Over 95% of the hill is groomed, and although there is no official tree skiing, adventurous skiers manage it anyway. There are 10 Beginner Green runs (the largest, Voyagers Highway is in itself the size of many Midwest ski areas), seven More Difficult Blue runs, seven Most difficult Black runs, and four Expert Double Diamond runs primarily because of moguls. The facilities normally found at the hill base are on top of the hill
Design–Expert the number of test runs needed. ANOVA is provided to establish statistical significance. Based on the validated predictive models, a numerical optimizer helps the user determine the ideal values for each of the factors in the experiment. Design–Expert provides 11 graphs in addition to text output to analyze the residuals. The software determines the main effects of each factor as well as the interactions between factors by varying the values of all factors in parallel. A response surface model (RSM) can be used to map out a design space using a relatively small number of experiments. RSM provides an estimate
