where operating profit and launch costs are the appropriately discounted range of cash flows to time T 0. [11] The DM Option can also be interpreted as a logical function. Frequently the simulation is provided by a Monte Carlo function embedded in a spreadsheet, such as Microsoft Excel. The Excel logic function for a DM call option is:

Taller sheet pile walls will need a tie-back anchor , or "dead-man" placed in the soil a distance behind the face of the wall, that is tied to the wall, usually by a cable or a rod.
This histogram provides an estimate of the shape of the distribution of the sample mean from which we can answer questions about how much the mean varies across samples. (The method here, described for the mean, can be applied to almost any other statistic or estimator .)
Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
