第一类误差,也称为 α错误、“弃真”错误。是指在统计检验时,在原来的假设为真的情况下,作出了拒绝原假设的一种错误推断。
运用数理统计学的误差传递公式,推导出了组合梁截面抗弯承载力统计参数的计算公式(以第一类截面为例)。
Take the first cross section as an example, and the calculation formula of flexural capacity of composite beams is obtained by using the error transfer formula of mathematical statistics.
模拟结果表明,当误差正相关程度较高时,两种新检验在具有较小的第一类错误概率的同时,具有较大的功效。
Our simulation results show that for high positive errors correlation cases, these new tests have lower type-1 error and large power than modified F-test.
