The Estimation of Parameters

摘要: In this section we develop the methods necessary for applying theory of Sections 1 and 2 to concrete migratory systems. As already indicated regression analysis consists two parts: In first part (that is in Section 3.1) all parameters theory, which directly relate migration process, are estimated by comparison with empirical data. The explicit form probability transition rates consisting mobilities utilities turn out be functions regions involved time. The intention second (see 3.2) provide insights into dependence process on socio-economic key-factors. Of course it well-known that difficult if not impossible establish a direct unique causal relationship between situation dynamics. Instead expect many influences merge different intensities producing behaviour. Therefore take degree regional temporal correlation variables as an indirect measure their relevance generating or influencing migration. particular certain key-factors utility function u i (t) global mobility v0 will determined simul-taneously method ranking introduced.
