Thanks a lot.I was learning how to use R in Sage recently. The norm function of R provides a normal distribution of two parameters mean and sd.So I would use the R interface in Sage instead. But I have problem ploting wuth R interface in Sage. I use the folliwing code to plot a histogram hut faile

I am so sorry that I forget about this as the 'gaussian'distribution in sage only take one parameter sigma. I think 'normal' distribution should have two parameters mu and sigma. Kannappan Sampath 提到: >On Tue, Jun 24, 2014 at 8:28 PM, gofortu...@gmail.com >wrote: > >In fact,I like the pure m

In fact,I like the pure math part of sage.But it would be better if I can do some modelling on sage. Recently I was reading the reference manual of probability, but I found that RealDistribution does not support normal distribution. RealDistribution supports uniform, gaussian,rayleigh,lognormal,

Thank you,Kcrisman. I am so sorry that I did not ask my question clearly, but luckly you understand most of my question. The link to publication that use sage is great. I do hope sage can have a lot of packages like R. It seems that sage focus on pure mathematics more than application.I do not fi
