情况1:如果 Alpha变得更严格(即 Alpha 的值越小),在拒绝 H0 方面的限制就会更严格,而在不拒绝 H0 方面的限制会更小。这会导致不太可能拒绝 H0,更有可能不拒绝 H0。 在真实情况中 H0 为True的情况下,拒绝 H0 的可能性较小会导致Type-I错误比以前更少。 在真实情况中 H0 为 False 的情况下,更可能不拒...
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...
Type I and type II errors occur during statistical hypothesis testing. While the type I error (a false positive) rejects a null hypothesis when it is, in fact, correct, the type II error (a false negative) fails to reject a false null hypothesis. For example, a type I error would conv...
第一类错误，又叫作Type I Error，False Positive. 这类错误的定义为：原假设不为真的情况下，你说原...
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 ...

Type I error is the rejection of a true null hypothesis (also known as a "false positive" finding), I类错误是拒绝了本为真的 Null Hypothesis Type II error is failing to reject a false null hypothesis (also known as a "false negative" finding). 1-power。
NewDurationDayTime (bool isPositive, int day, int hour, int minute, int second); Parameters isPositive Boolean Set to false to create a negative duration. When the length of the duration is zero, this parameter will be ignored. day Int32 Day of Duration. hour Int32 Hour of Duration...
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 ...
