De invloed van sociale zekerheid op migratie is een onderwerp dat tweespalt genereert in politiek en debat. Maar wat is feit en wat is fictie? Onderzoek laat zien dat sociale zekerheid geen belangrijke drijfveer is voor immigratie. |

Graduation of Mortality See also: My article in Vector Mortality tables are usually graduated for either practical or scientific purposes. The formulae, in which the mortality is expressed as a function of x (= age) are often of the type (Makeham's law): mx = A + B.cx (force of mortality) with A, B and c as parameters. Finding the values of those parameters from the crude material is the hard part. King-Hardy's method is a suitable way to transform this power function into a linear equation system; it is solved here by way of a least square K-runtime function. See also E.Zwinggi - Versicherungsmathematik When invoked, one will find four controls in the bottom part. The first two controls act like a spinbox, the two right most controls simulate the Windows-locator. The challenge is to find as large as possible ranges for making the "law" valid. Later, famous methods came from Thorvald N. Thiele, published posthumously in 1910, and more recent approaches and remarks can be found at W.J. Willemse. Recommended for Africa: G.M.K.
