Hello, I know only these EPI INFO. I believe that may be used, as it allows the production of basic statistics, variable tests of statistical significance. It also allows the development of maps with the statistical information produced.

Ecological statistics is a very broad field. I personally would use R, if you are planning to continue doing this type of analysis in the future. It is an extremely flexible system and is quickly becoming the "standard software" for statistics in many different fields including ecology. In addition it is free and runs on most operating systems Windows, Linux, OS X, Solaris with no difficulties and even on micro-controller boards like the Raspberry Pi 2 with some difficulty for simpler jobs.

I have used PASW (new name for SPSS)  and I if you meant Origin, I have also used it. Origin is mainly a system for plotting with some statistics added. PASW comes with different modules, and depending on the licence you have it may not cover all your needs. My own experience is that it is unwise to spend too much time learning a commercial system that because of its high cost may not be available to you at a future workplace or if you decide to work independently as a consultant or in a non-profit or similar organization. R is free, but there is now also a version from Microsoft that is just the same program with some "quality assurance" from Microsoft and a very few performance tweaks.

R software

Dear Andem,

I agree with Pedro José Aphalo. R is a flexible and customizable platform that brings a vast set of basic tools for statistic analysis and is fairly easy for the user to add more and more tools, programs and functions to it. One will have to spare some time on learning the language, once R needs line commands to work. But, there are interfaces that can make the task easier, like Rstudio.

R has powerful graphical capabilities and may run even very complex models with the aid of accessory softwares, such as WINBUGS, JAGS and STAN. Although the learning curve is steep, the gains in analysis quality and the control you will have on it will by far overcome any difficulties you may have at your first days of study.

Hope you join this intellectual adventure. Enjoy the learning and get the most of it.

Best regards,

Thiago Timo.

for the more basic statistics, R Commander = Rcmdr may ease learning R since it provides SOME basic user interface like the softwares you name, do, but also provides you with the R code that your button actions would translate as . http://www.rcommander.com/
