مقالة وصول حر Reply to Dr. Al- Youse! Comment on: A Stochostic Approach to the Estimation of the Number of Survi-vals at Each Age[l](دار جامعة الملك سعود للنشر, 01/01/1989) Dr. M.F. Abou EI-FetouhWe begin with the point that some studies of the number of survivals at each age,
has approached the problem assuming it to be deterministic phenomenon as rep-resented
by Makeham's law. Dr. Al-Yousef has treated the problem in his paper
entitled "The analytical adjustment of life tables"[2] by using deterministic model to
represent the stochastic phenomenon of birth and death. How can we use a
mathematical expression for a random process!. This is questionable and wrong. Dr.
Al-Yousef has failed to take into account the random element explicit in his model.
He considered the number of survivals at each age as a mathematical and not a ran-dom
variable.مقالة وصول حر Reply to Dr. Al- Youse! Comment on: A Stochostic Approach to the Estimation of the Number of Survi-vals at Each Age[l](دار جامعة الملك سعود للنشر, 01/01/1989) Dr. M.F. Abou EI-FetouhWe begin with the point that some studies of the number of survivals at each age,
