After adjusted by the C-reactive protein level in multivariate model, the elevated MPO activity of 10 units was attributed to an increased cardiovascular risk for 20.4%.
单位根检验是计量经济学中检验时间序列数据平稳性的最重要工具，而协整检验则是用来判断非平稳变量之间是否存在长期均衡关系的常用方法。
As an important tool of testing time series stationarity, unit root test is always used, and cointegration test is also often implied for judging long equilibrium between nonstationary variables.
可能有人会争论说em单位才是CSS中的第一个变量，因为它引用了font - size的值。
Some would argue that the em unit was actually the first variable in CSS, as it referred to the value of font-size.
实际变量是以物质单位衡量的变量。
单位根检验结果是否可信，直接影响后续的协整建模过程，从而影响变量之间长期的结构均衡关系，以及短期的误差修正机制。
The results of an unit root testing can directly influence the process of modeling, the long-run equilibrium relationship and the short-run error correction mechanism.
