t-value: The t-values for testing if the parameter equals zero, where t = the parameter estimate/standard error of the estimate.

p-value: The corresponding p-values.

R-square: R-square = (SYY-RSS)/SYY.

Adj. R-square: Adj. R-square = 1-[(1-R-square)*(N-1)/(N-k-1)].

Root-MSE: Root-MSE = estimated standard deviation.

可以，其实我用mathemattics也做了一多元回归,在mathemtics 中是可以进行多元高次回归,不知道你用不用这个软件,

那句话的意思是一般第一列是非独立变量（就好象我们常用的y值），你必须选择独立变量，就是自变量的那几列．
做多元回归的时候，你必须选择充当自变量的那几列．

那你把独立变量放到第一行就可以了
