Statistix

"Statistix (which I've used for may years) is great for EXPLORATORY data analyses."

Commentaires: Please see my review.

Avantages: Statistix is my "go to" program for most initial analyses of experiment data. For me, its best features are easy access to graphical looks at the data and the "Omit, select, restore" command. I always tell students, "before you run any statistical analyses, GRAPH your data," and Statistix makes that really easy. Although I don't use Statistix to produce figures for publications, I'll often model my publication graphs on those quickly drawn with Statistix. I find "Omit/select/restore" incredibly useful for exploratory analyses because it allows me to partition data sets and focus analyses only on portions of them WITHOUT having to save a multitude of partitioned files under a large number of different file names. I also like the very clear menu layout, and the ability easily to run both parametric and non-parametric analyses, and to transform data. The selection of ANOVA designs is very good, as is the selection of post-hoc tests offered. Another feature that facilitates explorations of data by regression are tools such as "Best-subset linear regressions" that allow finding the independent variables that explain the most variance. The best experience that I've had with Statistix was using it to re-analyze a student's analysis of a complicated three-factor, blocked design that had been analyzed with "R." Statistix refused to run the analysis, giving the message that two treatments were aliased, which we hadn't realized (and "R" did not reveal).

Inconvénients: There is very little that I dislike about Statistix when using it for data exploration. The main thing is that sometimes I want to look at a quick graph to compare more groups than a particular graphic will allow (perhaps comparing many lines instead of a limited number), or using something like box-and-whisker plots for a two- or three-factor design without having to re-code them as if they were multiple levels of a single factor. Although I do not produce publication-quality graphs with Statistix, I do NOT WANT it to implement the large number of formatting options that would be needed for that purpose. I would be afraid that would overly complicate what now are exceptionally easy to use graphs that greatly favor rapid data exploration. The only time I couldn't use Statistix for a publishable analysis was when I had a two-factor, repeated-measures design with unequal sample sizes per treatment (because of plant mortality). My solution had been to randomly eliminate data so that all treatments had equal numbers of plants, and then to argue that the diminished replication made the analysis conservative. But reviewers wouldn't accept that argument, so I had to use some other statistical software that implemented restricted maximum likelihood methods (which Statistix did not) in order to accommodate my unbalanced data.

"Intuitive, fast, easy to use, high-value statistical analysis software"

Commentaires: It enables me to do most of the analyses I need to do on data sets very quickly and efficiently. It is also very useful for quick visualizations of data, and for quick power analysis when planning studies.

Avantages: Statistix is my statistical analysis software of choice for most applications.
It is very easy to use with a nice intuitive GUI interface and a logical clean menu structure.
The platform is very very fast.
It has an excellent breadth and depth of analytics tools for a wide variety of applications.
The cost is very reasonable.

Inconvénients: There is very little if anything to actually dislike, but there are a number of things that would be great to see built into the Statistix platform. For example...
I'd like to see an even richer (broader and deeper) set of graphics and visualization tools and output, including 3D/4D/5D scatter-plots, and more editable, interactive and higher resolution charts - including the feature of cursor hovering underlying summary data display, zoom in/out on x-axis values, histograms integrated with scatter plots and frequency count graphics integrated into time-series charts.
Drag-and-drop functionality to manage data, as well as to build and change the output charts and tables would be very useful.
I would like to see a multi-proportions test for 3 or more proportions with full pairwise comparisons.
I would like to see capabilities built in to support monte-carlo / stochastic modeling, as well as bootstrapping.
I would like to see a deeper, broader power analysis set of tools.
I would like to see a broader and deeper set of Lean and SixSigma features and tools.
I would like to see a feature set that enables automated, real-time API connectivity with other digital platforms/data sources along with automated analytics run from a user pre-determined set of methods, input values and output formats delivered to a user pre-determined alert and notification list.
There are more things on the "want-list", but these are some things higher on that list.

"IT IS A SUITABLE PROGRAM"

Commentaires: i have a good experience of the programm

Avantages: The transaction is very simply and you can get the information easly

Inconvénients: i compared it with the other and it was the best

"We have used SX for many years and find it an excellent statistical database and software. "

Commentaires: It permits analysis of data that is very user-friendly and well documented and statistical procedures that satisfy most of the primary needs of fisheries scientists.

Avantages: This is an excellent analytical software, and I highly recommend it. It is very user-friendly and well supported with help menus and explanations of the statistical analysis offered. Our biologists, technicians, undergraduate and graduate students have used the software and have found that it provides 80% of the analyses normally used in fisheries science. Customer support has been excellent; however, we continue to use versions 8 and 9 because we have found some issues with certain utilities in 10. As a research scientist and adjunct professor, I am very pleased to have the capabilities provided in the software, use it regularly in data analysis. My graduate students use it for 90% of their graduate-work analysis, which has been published throughout the primary literature. We routinely reference the use of the software in our scientific manuscripts and papers.

Inconvénients: Wish it had more utilities associated with more advanced statistical analysis. The software is highly capable, and I recommend it routinely to my undergraduate and graduate students. In a recent version (9 and 10), we found a utility lacking that was in the former versions. We contacted Customer Support, and they very quickly prepared a patch. So although there were some issues, they were dealt with immediately and appropriately. We do not use version 10 and would like to do so because it has many updated features that aren't as user-friendly as in versions 8 and 9, We have seen that some plots in version 9 do not present all the values; one value appears to be dropped, usually the lowest. This is a very minor problem, and given the tremendous capabilities of the software, we have not concerned ourselves with this minor problem. I have virtually no reservations in recommending this software to my colleagues, students, and graduate students.

"Statistix has been the primary statistical analysis software used in my lab since 1985. "

Commentaires: Please see comments in my review. Excellent software - highly recommended for anyone working in the agricultural sciences.

Avantages: Statistix is by far the fastest and easiest statistical analysis package to learn and use. It is highly intuitive, and allows one to effortlessly compare different options for data analysis (e.g., with or without transformation; various approaches for mean separation following ANOVA; parametric versus simple nonparametric tests, etc.). I find it an excellent teaching tool for illustrating these concepts to new graduate students. Undergrad research interns, too, quickly learn to use it. The program is powerful and versatile enough to accommodate nearly all of our needs (we work in applied ecology and agricultural entomology). It is very easy to get data into Statistix (e.g., copy and paste from Excel file) and get right to the analyses. Technical support is excellent. My lab members (>40 graduate students) have published >200 refereed papers in national and international journals. Statistix has served our needs very well.
