在假设检验的过程中,试图用观测到的样本数据来支持这个陈述成立。 参数假设检验 / Parametric Hypothesis Testing:概率密度函数的形式已知,用于检验感兴趣的参数是否在参数空间的指定子集中。 非参数假设检验 / Nonparametric Hypothesis Testing:总体的分布完全未知,检验方法不应依赖于总体分布的具体数学形式。 例如,检验样...
Selecting the sample size is important in hypothesis testing. The sample size chosen impacts the risk of Type I and Type 2 errors. The sample size also directly determines the confidence levels and the power of the test. The sample size formula can be resorted to arrive at the sample siz...

假设检验(Hypothesis Testing)是一种统计方法,用于评估关于总体参数的陈述或假设是否成立。它通常用于分析实验数据,调查统计样本,或研究总体特征。在假设检验中,通常有两个互相排斥的假设,它们分别被称为零假设(H0)和备择假设(Ha): 1. 零假设(H0) 这是一个默认的假设,通常假定没有效应、无显著性差异或没有关联。
Chapter 7 Inferential Statistics (Hypothesis Testing) The crux of neuroscience is estimating whether a treatment group differs from a control group on some response, whether different doses of a drug are asso- ciated with a systematic difference in response, or a host of other questions...

Discover the mathematical foundations of hypothesis testing. Learn how a test of hypothesis is defined and carried out and what criteria are used to evaluate it in mathematical statistics.
Different methodologies exist for hypothesis testing, but the same four basic steps are involved: Step 1: Define the Hypothesis Usually, the reported value (or the claim statistics) is stated as the hypothesis and presumed to be true. For the above examples, the hypothesis will be: ...
