一类错误(Type I Error)和二类错误(Type II Error)是统计学中常用的两种错误分类,通常与假设检验相关。 一类错误(Type I Error): 定义:拒绝一个实际上是真实的假设的错误,也称为假阳性(False Positive)。 例子:在医学测试中,假设零假设是患者没有疾病,一类错误就是错误地得出患者...
False Positive. 这类错误的定义为：原假设不为真的情况下，你说原假设是真的。比如说，“这个男人怀...
当小男孩前几次捉弄村民的时候,明明没有狼,村民们却误以为有狼,这是上了false alarm的当,专业术语叫false positive,又叫Type I error。 当狼真的来了,小男孩求救而不得的时候,村民们误以为狼没来,这是吃了missed detection的亏,专业术语叫false negative,又叫Type II error。 记住它:村民们先犯了Type I ...
它是指统计检验时,对实际上没有发生的研究结论作了正确的结论,这种情况称为错误定义1(Type I Error)。一般来说,Type I Error是采用错误的零假设而拒绝正确的零假设的结果。它也被称为“假正(False Positive)”错误,也就是表示某一问题存在,实际上却不是。 Type I Error源于统计学家R.A.Fisher在1925年发表...

When there are a lot of questions there is a high probability of a false positive. Two subsequent studies that specifically tested for the association were negative. A simple explanation[weaselwords]is that the initial finding was chance due to multiple questions being under consideration. Those ...
支持科学计数法:Number 类型可以使用科学计数法来表示非常大或非常小的数值。例如,可以使用let largeNum: number = 1e6;来表示 1000000。 具有特殊数值:Number 类型还具有一些特殊的数值,如正无穷大(Infinity)、负无穷大(-Infinity)和非数值(NaN)。这些特殊数值可以通过Number.POSITIVE_INFINITY、Number.NEGATIVE_INFINIT...

The difference between a type II error and a type I error is that a type I error rejects the null hypothesis when it is true (i.e., a false positive). The probability of committing a type I error is equal to thelevel of significancethat was set for the hypothesis test. Therefore, ...
