- Abstract
Affinity has a long history related to the social behavior of human, especially, the formation of social groups or social networks. Affinity has two meanings. The first is a natural liking for or attraction to a person, thing, idea, etc. The second defines affinity as a close relationship between people or things that have similar appearances, qualities, structures, properties, or features. Affinity here is simply defined as the distance/closeness between any two objects: the distance measurement could be geometric or abstract, or any type a decision maker prefers. A new forecasting method without historical memory, based on game theory and affinity set is originally proposed. The prediction performance of this new model is compared with the simple regression model for their performances on decision of buying in or selling out stocks in a dynamic market. Interestingly the qualitative model (affinity model) performs better than the quantitative model (simple regression model). Possible affinity set applications are provided as well in order to encourage readers to develop affinity models for actual applications
