Comparison of Piecewise Regression and Polynomial Regression Analyses in Health and Simulation Data Sets

Öz

Objective: Piecewise regression, which one or more pieces are combined in breakpoints, is widely used as a statistical technique. It was aimed to compare piecewise regression analyses and polynomial regression analysis using both simulated data and real data sets.

Material-Method: In the application step of the study, algorithms were created by using R software for simulation practice. Polynomial and piecewise regression analysis methods were compared using data sets with n=100 units and 1000 times running simulation. In addition, estimation performances of piecewise and polynomial regression built by using the data sets which contained in the number of tuberculosis cases according to age in 2010 year and the number of measles cases from 1993 to 2015 years in Turkey were compared.

Results: It was found that there was a significant difference between all of the polynomial and piecewise regression models (p<0.001). The  values of piecewise regression models were higher than polynomial regression models; MSE, AIC and BIC values were observed to be lower. According to the result of both simulation and real data set applications, piecewise regression models which were generated according to optimal knots were found to have better estimation performance than polynomial regression models according to , MSE, AIC and BIC criteria.

Conclusions: This study revealed that data analysis with piecewise regressions having optimal knots provided statistically superiority, although polynomial regression methods are preferred in the field of health studies mostly.
