The proportions of the variance explained by the models ranged from 21% to 28%.

It is found that the more the variance explained by the linear model, the smaller the standard deviation of regression coefficient.

拟合方差与回归系数标准偏差存在明显的相关关系。线性模型能解释的方差越大，回归系数标准偏差越小。

Then the data were analyzed by the absolute principal component analysis (APCA) to evaluate principal components and the percent variance explained by them.

The explained variance of this residual yield by climate is generally about 50%, which is very close to the average I found for corn, soybeans, and winter wheat.

In fact, the Brinson, Hood and Beebower study a lot of advisors chant about demonstrated that 90% or more of the variance in returns among large pension plans was explained merely by their allocation to stocks, bonds and cash.
