区间估计(Interval Estimate)和置信水平(Confidence Level) 在点估计的基础上,在一定的置信水平下,给样本统计量加上一个区间范围作为总体参数的取值范围,这个区间叫置信区间(Confidence Interval)。 而置信水平是构造多次置信区间,其中包含了总体参数的置信区间占了多少比例?比如想要估计学生平均成绩,抽取了100个学生样本,...

casted value: The larger the confidence level, the wider the interval. Therefore, Observation 1 is not correct. Observation 2 is correct. The greater the standard error of the estimate, the greater the standard error of the forecast.第一句话的意思不就是说confidence level确定,Intervall不变么?
Level of confidence In practice, the coverage probability is seldom known because it depends on the unknown parameter (although in some important cases it is equal for all parameters belonging to the parameter space). When the coverage probability is not known, it is customary to compute the con...
按一定的 概率 或 可信度 (1-α)用一个区间来估计 总体 参数所在的范围;该范围通常称为参数的可信区间或者置信区间(confidence interval,CI),预先给定的概率(1-α)称为可信度或者 置信度 (confidence level),常取95%或99%。
Confidence level = 1 − a 例如,如果构建显著性测试 p < 0.05的话,就要建立置信水平为 95% 的置信区间,则测试人确信 100 次估计中有 95 次将落在置信区间指定的上限和下限之间。 置信区间的计算公式如下: CI = 置信区间the confidence interval
