Linear regression methods and error analysis for paleodose of pottery

陶器古剂量P包含等效剂量Q和超线性修正I两个部分,为了提高古剂量测量的准确性,正确地计算古剂量的测量误差,本工作测试了10个古陶片样品,利用线性回归方法计算等效剂量Q和超线性修正I,并对不同的古剂量计算方法进行误差分析和评估。研究表明,线性回归方法(包括归平法和平归法)计算陶器古剂量的准确性优于目前采用的常规法;通过几种不同方法的误差比较和分析,归平法所得误差较其它方法更严谨、合理。该研究在提高古剂量测量的准确性和正确计算古剂量的测量误差两方面具有重要的意义,使得古剂量的测量更加合理,符合数理统计规律。

The paleodose of pottery comprises the equivalent dose Q and a superlinearity correction L For the purpose of measuring the paleodose accurately and calculating the error of paleodose correctly, the linear regression method was used to calculate the equivalent dose and the superlinearity correction for 10 pieces of pottery. The errors in various methods were analyzed. The results indicate that linear regression method is more accurate than the currently used normal method for calculating pottery paleodoses. Comparison of the errors calculated with different methods showed that the method averaging after linear regression is better than other methods in calculating paleodose errors. This study is important for improving the accuracy of paleodose measurements and calculating paleodose errors correctly. It makes paleodose measurement conforms to statistical laws.
