Is anyone familiar with a linear regression module for perl? I am not interested in viewing graphs. I just want to feed in a CSV file with the x,y coordinates and whatever other data is recorded. The code should figure out what the slope of the regression line is based on the points and they, for example, I would look across the x-axis and find the number 15 and then find the corresponding value on the y-axis. I'm only interested in that y-axis value, the r-value, and the number of points plotted. Again, I only want the returned information, not actually view graphs.
