I have empirical Bayes estimates for slopes and intercepts for a number of subjects and I would like to plot the slopes and intercepts with confidence ellipses. These ellipses would be based on the confidence intervals for the slope and intercepts (forming the major and minor axis of each ellipse), and the correlation in the slope and intercepts.

I am trying to make a graph with 4 scatter matrixes plots and couldn't do it. While trying to find a solution for this I also came across the idea of giving different values to the same argument for each of the lower and upper function but couldn't do it.

I''m getting errors whenever the user chooses, for example, April 31st ( since there is no 31st in April, navicat freaks out ), there MUST be a method that ruby has that would allow me to validate a date before I submit to navicat.
