Research of Software Estimate Model COCOMOII Based on Bayesian Calibration Algorithm
Jin Chen · Journal of Langfang Teachers College · 2008
Software cost estimate model COCOMOⅡlays the foundation for software development's in cost estimate.To further enhance the estimate precision of COCOMOⅡ,Bayesian Calibration Algorithm,one multiple regression analysis method,is adopted to calibrate the model.It arrives,on the basis of both apriori information and sample information in a logically consistent manner,at the posterior result which can makes the estimate more accurate.The experimental results shows that the COCOMOⅡmodel after Bayesian Calibration Algorithm further improve the accuracy of the data.
