? 2) How does Matlab compute the p-value? The p-value(which should be smaller than the critical value of the F statistic in order to have a significant test) is normally the area beneath the right tail of the f distribution at the F-value, if I understood the...
Regression analysis is a form ofinferential statistics. The p values in regression help determine whether the relationships that you observe in your sample also exist in the larger population. The linear regression p value for each independent variable tests the null hypothesis that the variable has...

The threshold value for determining statistical significance is also known as the alpha value. Example: Statistical significance Your comparison of the two mouse diets results in apvalue of less than 0.01, below your alpha value of 0.05; therefore you determine that there is a statistically signific...

回归样条(regression spline)本质上是一个分段多项式,但它一般要求每个分段点上连续并且二阶可导。 即:设自变量数据的范围在区间[a,b],并根据需要分成k个段:a = t0 < t1 < … < tk-1 < tk = b,在每个区间 [ti-1,ti) 分别用一个多项 Si(x) 式表示,则回归样条 f(x) = Si(x) 当 x∈[ ti-...
