An econometric model to forecast electricity consumption in Zimbabwe through the year 2010 using 20 yr of data (1965–1984) is presented. The model is a nonlinear dynamic system of simultaneous equations relating macroeconomic and demographic variables to electricity consumption. Its purpose is...

Genetic programming (or GP) is a random search technique that emerged in the late 1980s and early 1990s. A formal description of the method was introduced in Koza (1992). GP applies to many optimization areas. One of them is modeling time series and using those models in forecasting. Unlike...

An investigation of the prices of eight individual stocks showed that pricechange returns are significantly less complex than are time-dependent returns. Timedependent returns computed every 15, 30 and 45 minutes were found to be more complex, using a complexity measure. Complexity is quantified...
