Hi, I'd like to calculate a correlation coefficient between two variables in a vtu data set. I am not experienced with statistics but the Pearson correlation coefficient looks suitable. So I just need the covariance and standard deviations.
The Paraview Multicorrelative Statistics filter seems to give the covariance, but I can't find a filter that gives the standard deviation. The Descriptive Statistics filter is supposed to give standard deviation according to the documentation, but I am not getting it when I run the filter. I am referring to this documentation: http://www.paraview.org/Wiki/Statistical_analysis I am currently running both paraview 4.0.1 and 5.0.0. They give slightly different outputs from the statistics filters, but neither gives me the standard deviation (unless it is hidden in M2, M3 or M4? I don't know what these are). Can anyone help with either my lack of standard deviation or an alternative way to calculate a correlation coefficient? Thanks, Rupert Gladstone
