At the same time, considering these two factors correlated with other factors that influence market return, there may be co-linearity in our regression equations if we ignore this phenomena.
Additionally the linearity of the measurement by PMS has been verified by analyzing CO and CO2 at various concentrations based on a single-point calibration.
图五所示为采用过程质谱基于单点校正在不同浓度测量CO和CO2的线性度的测试结果。

For geometrical non-linearity, the co-rotational formulation approach is utilized.
