Analyse-it for Microsoft Excel (sharewae) http://lib.giveawayoftheday.com/Analyse_It_For_Microsoft_Excel_53309/ is a statistics package program. You start analysis and then discover an observation to exclude, that analysis should focus on a subset where an effect is present, that the latest data from a live process needs to be added, or that a different model should be used. A feature that makes Stata different from all of the programs in its class, is that you have to enter all the information manually when working on new data. In an "Import/Export" format era this might seem quite antique, specially when the supported "Import/Export" format is the ASCII code created on other documents format (xls). For the new statistics generation this might seem challenging, but this is one of the programs strengths. Once you enter the data you will work with, it will be saved so you can work with it all the time, using the same variables for multiple graphics and calculations. All the data input have to be done through "commands" that in a "single-click" era is quite strange. However, once you become familiar with the command syntax you can start creating reports. The reviewed version is STATA IC, you can chose a version depending on your needs and infrastructure/data base resources. Review licensed from Publisher description Stata is a complete, integrated statistical package that provides everything you need for data analysis, data management, and graphics. Stata is not sold in modules, which means you get everything you need in one package. And, you can choose a perpetual license, with nothing more to buy ever. Annual licenses are also available. Stata 12 adds many new features such as structural equation modeling (SEM), contrasts, ARFIMA, business calendars, chained equations for multiple imputation, contour plots, automatic memory management, importing and exporting of Excel files, and more
Instat+ (freeware) http://lib.giveawayoftheday.com/Instat_26879/ is a general statistical package. It is simple enough to be useful in teaching statistical ideas, yet has the power to assist research in any discipline that requires the analysis of data. Instat+ provides a relatively gentle introduction to using statistics packages, and can be a useful "stepping-stone" towards other, commercial, statistics packages. Instat+ is designed to support the teaching of statistics. It includes features to help explain many of the key concepts, such as confidence intervals, that users often find confusing. Furthermore, its teaching menu provides a resource pack of ideas, some that use Instat, but many that can be used with any statistical software. Instat+ includes many special facilities for the processing of climatic data, supported by a 400 page guide, included with the package as a help file. These facilities have formed the basis of numerous agroclimatology training courses, in the UK, Kenya, Niger, Algeria, Syria, the Philippines and elsewhere.
