I would have preferred either a loess with less smoothing (controllable by varying the parameter ‘span’ in R) or, even better, a plot of the autocorrelation and partial autocorrelation functions, to summarise this series.
WebCentering polynomials is a standard technique used when fitting linear models with higher-order terms.

The first derivativeis the steepness of the curve at every X value. The derivative is positive when the curve heads uphill and is negative when the curve heads downhill. The derivative equals zero at peaks and troughs in the curve. After calculating the numerical derivative, Prism can smooth the results, if you choose. … See more If you import a curve from an instrument, you may wish to smooth the data to improve the appearance of a graph. Since you lose data when … See more Smoothing a curve can be misleading. The whole idea is to reduce the "fuzz" so you can see the actual trends.
