Boraine, H. Artificial neural networks are powerful tools for time series forecasting.
The problem addressed in this article is to do multi-step prediction of a stationary time series, and to find the associated prediction limits. Maree, J.

South African Statistical Journal, 29, is utilized Du Plessis, K University of Pretoria , The analysis of a time series is a problem well known to statisticians. Neural networks form the basis of an entirely non-linear approach to the analysis of time series. It has been widely used in pattern recognition, Mahomedy, Z.

In its "founding" years, the Fellowship was guided by its executive officers and an Advisory Council, then later by a Board of Directors. The first council was formed of Evangelical leaders V. Raymond Edman, Dawson Trotman, R. McQuilkin, Jack Wyrtzen, and C.
Stacey Woods. In the Council was enlarged and became known as the Board of Reference. Active membership in MAF was comprised of pilots, mechanics, technicians, office staff, etc. Admission to membership required an age of twenty-one thirty-two years maximum in earlier MAF history , compatibility with stated principles and practices, agreement with the statement of faith, and screening by MAF leaders and selection by a nominating committee. Associate membership was open to any interested party, but did not include voting privilege. Qualifications included age, Christian technological education such as Moody Bible Institute's Missionary Technology degree or from Le Tourneau College, or from certain reputable secular schools like the Spartan School of Aeronautics , and technical proficiency as commercial pilot with flight AP mechanical rating.
Pilots underwent several months of orientation, including to mountain and desert conditions to prepare them for field work, preparation for transition to an unfamiliar culture, instruction in budgeting and proper record-keeping, and training to be an unofficial ambassador for Christ in working with foreign populations and governments.
