摘要: 天文学研究经常用到许多误差分析方法,使用时需要注意他们的适用条件.这些方法大都基于统计学原理,既有较传统的参数估计、置信区间的方法,又包括基于模型参数的暴力搜索法、变化卡方法、费希尔矩阵法和蒙特卡罗方法,等等.他们成为天文工作者数据分析的利器.

关键词: 统计方法, 误差估计, 误差分析

Abstract: There are many error estimation methods commonly used in astronomy. We must pay attention to their applicable conditions before using them. Most of these methods are based on the principle of statistics, which include traditional parameter and confidence interval estimation, and brute-force grids, varying chi-square, the Fisher matrix, and Monte-Carlo methods in the case of model-based parameter estimates. They have become the most powerful tools in data analysis for astronomers.

Key words: statistical method, error estimation, error analysis
