Matlab pearson correlation plot
WebThe matrices RL and RU give lower and upper bounds, respectively, on each correlation coefficient according to a 95% confidence interval by default. You can change the confidence level by specifying the value of Alpha, which defines the percent confidence, 100*(1-Alpha)%.For example, use an Alpha value equal to 0.01 to compute a 99% … WebHere’s a detailed description of each of the result windows: Correlation plot. A radial profile plot will be displayed, it contains the radial profile of the original cross-correlation image (blue line), the radial profile of the cross-correlation after subtraction of random associations (green line), and a Gaussian curve fit to the subtracted profile (red dashed …
