观测值

The residual value is the observed value at the center minus this average.

从圆心上的观测值减掉这个平均值，就得到剩余值。

Results show that calculations are in good agreement with observations.

机关表明计算值与观测值较好地一致。

The main regression and the auxiliary regression should use the same set of observations.

主回归和辅助回归必须使用相同的一组观测值。

The standard deviation measures spread by looking at how far the observations are from their mean.

标准偏差可查看各个观测值离均值有多远，衡量数据的散布。

Area can be calculated using measured data or file data ( Coordinate data ).

可使用直接观测值或文件数据 （ 坐标数据 ） 来计算面积。
