Median rainfall (mm) from 1960 to 2010. Superimposed on the plot in red is a LOWESS regression curve of rainfall against year. Note that this graph contains two separate axes: one for median annual rainfall and one for LOWESS smoothed annual rainfall. LOWESS is a polynomial smoothing technique that fits weighted least squares linear regression lines to localized subsets of data to describe deterministic variation in the data point by point. The power of this technique is that it takes into account neighbouring points of each point in determining the fit and repeats the entire procedure for each data point
