I'm developing several stats arb related strategies and need some off-the shelf software that will allow me to run price dispersion, time series and other analyses on various markets. I am not a programmer and do not desire to become one. Hence, ease of use, in addition to robustness, would be my main criteria. Also, the ability to painlessly download historical prices from one or more of the popular data vendors would obviously be a requirement. I recall using Minitab when I took stats, but that was several years ago (I believe it was dos based at the time) and my memory of it is hazy at best. Would that suit my needs or are there better alternatives? Thanks.
