请问做一个岭回归
rxridge price weight length mpg ,msteps(1)
RXridge: Shrinkage Path has Qshape = 0.00
RXridge: Adjusted response sum-of-squares = 73
RXridge: OLS Residual Variance = .67016457
RXridge: Variance of Principal Correlations = .00918034
MCAL = 0.000 ... True OLS Summed SMSE = .31583952
MCAL = 1.000 ... Estimated Summed SMSE = 1.1450446
MCAL = 2.000 ... Estimated Summed SMSE = 2.2285109
MCAL = 3.000 ... Estimated Summed SMSE = 2.604475
RXridge: Estimated Sigma = .8186358
RXridge: Uncorrelated Components... Number of obs = 0

请问 c1 c2 c3 的系数是岭回归后 weight length mpg 的系数么?另外,上面的K是多少啊?
谢谢
