The line is just an estimate. 1 comment ( 11 votes) Upvote Downvote Flag Nettet31. mar. 2024 · As the line will go through the point (mean (x),mean (y)) this allows us to calculate the value of the slope: pca.slope <- pca [ 2, 1] / pca [ 1, 1 ] pca.intercept <- mean (y) - (pca.slope * mean (x)) Once we have these values, we can plot the line on the scatter plot in the same way as before: ggplot (data) + geom_point (aes (x=x,y=y),colour ...
NettetBoth models appear to fit the data well, and the residuals appear to be randomly distributed around zero. Therefore, a graphical evaluation of the fits does not reveal any obvious differences between the two equations. The numerical fit results are shown below. As expected, the fit results for poly3 are reasonable because the generated data is ...
