It was based on an explicit micro-model of information spread, and on Monte Carlo simulation of the hypothesised spatial process. Using the original aggregated data and Hope-type tests of the ability of the simulations to capture the observed Hagerstrand traces the diffusion process by imitating it with numbers. Such imitation, leading to prediction or forecasting of the pattern of diffusion, is called a simulation of diffusion.

Abstract. Diffusionism assumes that (1) inventiveness is rare and therefore diffusion accounts for nearly all significant culture change and (2) certain places are permanent loci of invention and thus are more advanced and more progressive than other places. If, however, inventiveness and innovativeness are IOAIO IUSIO : COEMOAY GEOGAICA AOACES ISS 006642 IS 0 8604 68 C G. Clr, 84 blhd b G , rh rntd b .. thn & Sn, rh G.
