Mark the outlet on both sides of the stone. Then you can either use the tile saw, or an angle grinder with a diamond blade, to plungecut on all four sides. Start on the front of the stone and plunge until the cuts just reach the corners. Then flip the stone over and plunge-cut until the center piece falls out.
Predictive (forecasting) Descriptive (business intelligence and data mining) Prescriptive (optimization and simulation) Predictive Analytics Predictive analytics turns data into valuable, actionable information. Predictive analytics uses data to determine the probable future outcome of an event or a likelihood of a situation occurring.
I view this as just using terminology to help in better analytics process understanding. To me the difference between predictive analytics and prescriptive analytics is similar to what the difference between analytics and predictive analytics would have been before the invention of that term.
