How to add trendline to scatterplot? - MATLAB Answers - MathWorks LOESS (Locally Estimated Scatterplot Smoother) combines local regression with kernels by using locally weighted polynomial regression (by default, quadratic regression with tri-cubic weights). A scatter plot is a set of dotted points to represent individual pieces of data in the horizontal and vertical axis. On the other hand, if you've got a line which is "wobbly" and you don't know why it's wobbly, then a good starting point would probably be locally weighted regression, or loess in R. This does linear regression on a small region, as opposed to the whole dataset. summarizing the model fits. CI.color = "grey90", Plot, draw regression line and confidence interval, and show regression equation, R-square and P-value, as simple as possible, Trends in time series can appear in "autoregressive" processes, and for these processes the randomness of the process can occasionally construct trends out of random noise, and the wrong statistical significance test can tell you it's significant when it's not!
