Pattern and parsimony

Abstract. According to the principle of parsimony, model selection methods should value both descriptive accuracy and simplicity. Here we focus primarily on Bayes factors and minimum description length, explaining how these procedures strike a balance between goodness-of-fit and parsimony. .

The study adopted simplicity-parsimony idea as amalgam of simplicity and parsimony theories in analysing the trends and patterns of men’s sexual behaviour in Ethiopia, Nigeria and Zambia, the three countries selected from Eastern, Western and Southern parts of sub-Saharan Africa.

Syntactic simplicity, or elegance, measures the number and conciseness of the theory’s basic principles. Ontological simplicity, or parsimony, measures the number of kinds …explanations” is part of a larger tension between pattern and process. Pattern cladists or transformed cladists are one extreme end of the spectrum. They put forward the idea that cladistic (in this case = strict parsimony) methods do not need, and in fact are better off without an evolutionary (process) justification. There has been a tension among parsimony advocates between pattern and process, going back to the battles between numerical taxonomists and evolutionary systematists we talked about last time. Pattern cladists or transformed cladists are one extreme end of the spectrum.

More recently, Herbert Simon pointed n Simplicity, Inference and Modelling (2001) to the beauty in “finding pattern, especially simple pattern, in the midst of apparent complexity and disorder.” Simon construes parsimony itself as “pattern in the phenomena” and places it “at the root of what we mean by a scientific law.”Third, we ensure parsimony in the field by identifying joint mechanisms with regard to positive leadership styles and their practical translation into leader behavior when it comes to stimulating employee work engagement. Fourth, and practically speaking, our research model shows several pathways through which leaders may influence employee ...
