/* SAS Example 12: Three-Way ANOVA									 */

/* We wish to determine how successful a particular product will be
   once it's placed on the market. We ask consumers to give a ranking
   out of 100 that would determine how likely they would be to buy
   the product (100 for definite buy, 0 for never). We wish to
   examine three different factors on this likelihood - brand, price
   and positioning strategy.										 */
