There are two distinguishable kinds of errors: syntax errors and exceptions .

Python 中有两种错误：语法错误和异常。

However, in some situations, models are hard to satisfy these assumptions at the same time. We meet a number of random errors with serial correlation and heteroscedasticity in practical problems. The rationality of these assumptions for random errors is doubtable. Therefore, it is necessary to test for correlation and heteroscedasticity in regression, which is an important step of dealing with regression problems and plays an important role in theory and practice.

但实际问题中，回归模型很难同时满足Gauss-Markov的三个假设，人们在实际问题中发现许多随机误差出现序列相关和方差不同的现象，因此对回归模型的随机误差的独立性和方差齐性的假设产生了质疑，从而展开了回归模型的相关性和异方差检验的研究，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。

Interlanguage transfer, phonological universals and over-generalization are considered to cause the formation of phonological errors. Phonological errors take the following five forms: elision, addition, substitution, misplaced stress and over-precision.

语际转移、音韵普遍现象以及过度推广等因素共同作用导致中介语的音韵错误，具体表现形式有五种：省音现象、加音现象、替代现象、重音位置错误和过度精确现象。

Methods The effects of the reading error and the misalignment of the probes on the accuracy of measuring and all the harmonics of roundness were analyzed; The strategy and the algorithm for optimizing the parameters of the measuring system were proposed; The distribution and propagation patterns of the measured errors for all the harmonics of roundness were studied in detail; A software for correcting the errors caused by the measurement error of the angle positions of the probes and the sensitivity difference between three probes was presented.

分析了测头读数及角位置误差对圆度各次谐波及圆周各点测量精度的影响；提出了三点法测量系统的优化策略与算法；研究了三点法测量误差的分布与传递规律；提出了克服测头定位误差以及3个测头的灵敏度不一致影响的软件校正方法。

At present, most of the image watermarking algorithms based on the wavelet transform fail to take into account the shortcoming that the first generation wavelet transform used in image processing will introduce quantization errors inevitably, because of the storing characteristics of the image. Wavelet transform that maps integers to integers will not introduce quantization errors. Its time-frequency analysis method and multi-scale property accordant with human being vision system makes integer wavelet transform an ideal way for digital watermarking.

目前，大多数基于小波变换的图像水印算法没有考虑到第一代小波变换用于图像处理中不可避免的引入量化误差的缺点，而整数小波变换除了具有小波的多分辨率分析与人类视觉特性一致、具有良好的时频特性等优点以外，还避免了第一代小波变换用于图像处理中引入量化误差等缺点。

At the same time, there are a lot of criterions, such as: mean squared errors criterion, generalized mean squared errors criterion and Pitman criterion.

不同方法的出现就必然会引出优劣比较问题，相应的也就出现了一些比较不同估计的判别准则，如：均方误差准则、广义均方误差准则以及pitman 准则等。
