In this chapter, I am mainly concerned with time series in the first three categories, though many of the techniques can be applied to experimental time series where the index may be an integer or floating-point number indicating elapsed time from the start of the experiment. The simplest and...

回归保证数据的内插而不是外推: (Regression promises Interpolation of data and not Extrapolation:) Interpolation means applying the model to predict the value of a dependent variable on independent values that lie within the range of data already we have for analysis. 插值法是指应用模型来预测因变量...

The advantage of the single equation is that it may extrapolate better than a machine learned model. Interpolation such as a piecewise linear or cubic-spline function may be good if you don't need to extrapolate and there is little variability in individual data points. Here ...

Additionally, functions for quadratic spline interpolation, normalized cross-correlation, and optimization are applied to obtain the smile and keystone values. Findings indicate that the smile and keystone of a laboratory imaging spectrometer can be determined with sub-pixel precision. 4. Discussion In ...
