And some relevant geologic data regression equations for fault scarp formed in the past 2700 years have been obtained.

获得了相应地区断层陡坎的一些资料和距今2700年左右形成的断层陡坎回归方程。

The software can be used for not only petrophysical data regression analysis, but also logging data regression analysis.

该软件不仅可用于岩电实验数据回归分析，而且还可用于测井数据的回归分析。

An R2 near 1 indicates that a regression line fits the data well, while an R2 close to 0 indicates a regression line does not fit the data very well.

Using such intervals communicates the uncertainty within the model introduced by the scatter of the data instead of using the regression line that makes the relationship appear far more deterministic than it really is.

Important cases where the computational definition of R2 can yield negative values, depending on the definition used, arise where the predictions which are being compared to the corresponding outcomes have not been derived from a model-fitting procedure using those data, and where linear regression is conducted without including an intercept.
