What is a Test Statistic? The branch of math involving the recording and analysis of data is known as statistics. The meaning of the word ''statistic'' is a numerical measure, such as an average, that is derived from sample data. Atest statisticis a statistic that is calculated for the ...
For a 1-sample t-test, when the sample mean equals the hypothesized mean, the numerator is zero, which causes the entire t-value ratio to equal zero. As the sample mean moves away from the hypothesized mean in either the positive or negative direction, the test statistic moves away from ...
t-statistic for unit root testA.I. McLeod
1)这里为什么不是用t统计量,计算p1是否是significant的。而是用F统计量,考虑整个方程的解释力度? 2)如果是选用了F统计量,作为整体方程成立,怎么能辨别出解释力度是来自X1t,X2t还是来自μt-1(滞后一项)? 因为当X1t和X2t的combination已经能很好的解释方程,μt-1存不存在就不那么重要了。

T-test是指用T-statistic来做假设检验(hypothesis testing), 而T-statistic是根据model计算的，用来做检验的统计量。正常T-statistic应该在0假设(null hypothesis)为真时，服从T分布(T-distribution)。T-test时根据T-statistic值的大小计算p-value，决定是接受还是拒绝假设。基本内容：用来对计量经济学模型...
检验统计量(test statistic):用于假设检验计算的统计量。 例如:Z值、t值、F值、卡方值。 显著性水平(level of significance):当零假设为真时,错误拒绝零假设的临界概率,即犯第一类错误的最大概率,用α表示。 例如:在5%的显著性水平下,样本数据拒绝原假设。
