    An example is presented applying the cross entropy approach to data from Mozambique.

    An appendix includes a listing of the computer code in the GAMS language used in the procedure.

Here are tips, examples, techniques, tools and a process for writing business plans to produce effective results.Attain learning points for each leadership and management e Module, and gain a Level 3 Award, Certificate or Diploma once you have registered with the awarding body (via Accipio), secured enough learning points and passed the assignments. This free online guide explains how to write a marketing or business strategy, a basic business plan, and a sales plan, using free templates, tools and examples, such as SWOT Analysis, PEST Analysis, the 'Ansoff Matrix' and the 'Boston Matrix'.Some macro control totals are assumed known with error, and also all the row and column totals are assumed known only with error. * * The option used here is to detect any negative flows and net them out * of their respective symmetric cells, e.g.We assume that the user can specify a prior estimate of the standard error of the estimates of the row and column sums and of the macro control totals. * negative flow column to row is set to zero * and added to corresponding row to column as a positive number.Some projects are very substantial and equate to an autonomous (independent) business activity, in which case a business plan is entirely appropriate.
