MSTAT is a powerful tool used to simplify and enhance field and laboratory research. Researchers can use this software to generate the design of experiments (RCB, CRD, Lattice), print labels, and collect, organise, and analyse the data. MSTAT is a complete package containing all the programs listed below.
MSTAT Software and Operations Manual Cost $200
Licenses for additional computers are available.
You may obtain MSTAT by emailing an order, via FAX [517 353-5174], or sending to a request to the mailing address listed at the end of this web page. We accept purchase orders. Payment can be arranged by check or electronic fund transfer. We can NOT accept credit card requests.
MSTAT has two experiment design programs.
EXP Series will design experiments with from one to five factors and with up to four splits. It will also generate files for field books, labels, and maps and that can be edited, printed and/or stored.
VAR Series will design experiments with one factor. A square or rectangular lattice design can be created if the number of factor levels is latticeable (two or three replicates) or a one factor RCB design. VAR Series will generate files for field books, labels and maps that can be edited, printed and/or stored. The labels can be of three types - planting, harvest, or sampling.
Data collected from the field or laboratory can be entered using MSTAT's editor. If MSTAT was used to generate the experiment design, the file to receive research data is in the same plot order as the collected data. Data can be entered through the screen editor or by file transfer from data collectors or other software (ASCII Compatible). Once data are keyed in, they can be sorted, transformed, or edited using MSTAT.
MSTAT ANOVA programs include one/two way, factorial, lattice, nonorthogonal, hierarchical, nearest neighbor, and latin square. Other data analysis programs include T-test, LSD, Duncan's, Tukey's, Student-Neuman-Keuls, missing value estimator, orthogonal contrasts, summary statistics, principal components, regression, correlation, and multiple regression.
DATA FILE CREATION, EDITING, AND SORTING
There are many ways to enter, manipulate, and transform data. Data sets can be imported and exported in ASCII file format for easy transfer to and from other software (word processing, spreadsheet, and/or database). Data can be sorted (with up to 14 keys), transformed using equations, and manipulated to select specific types of data within a data set. A data set can be "printed" to a file, to screen or to a printer.
DESCRIPTIVE STATISTICS AND PLOTTING
MSTAT programs (STAT, MEAN, GROUPIT, FREQ, and TABLES) can be used to compute basic tables of statistics such as minimum, maximum, means, standard deviation, skewness, and kertosis. Data can be grouped into specific categories based on data values within a data set. Data frequency can be computed and histograms plotted. An x-y scattergram can be created and printed. MGRAPH is an additional routine that can be used alone or with MSTAT to create graphic output of data (line, pie, bar).
BR Series can be used to print books and labels for a plant breeding program. It will automatically keep track of parentage, generation, plot numbers, cross numbers and character index.
AC Series is a complete data management series for breeding materials. This series can be used to create a master accession file, crossing block files, and F1 to F9 breeding files. Field trials can be generated as well as six book styles and five types of labels. The Master Accession file includes breeding material information (accession number, descriptors, name, source and pedigree) and can be updated.
MSTAT has programs for multivariate analysis (Hotellings's T squared statistic, multiple discriminant and principle component analysis, nonparametric statistics).
ECON calculates the net benefit, risk, and marginal rate of return for experiments with treatments of varying costs.
SEASONS is an economic/seasonal regression program used to analyse seasonal commodity prices.
MSTAT is written in the C programming language and runs on DOS compatible machines with a hard drive (2 MB used by MSTAT) and a minimum of 512 K in RAM. MSTAT can be used under WIN 3.x, WIN 95, WIN 98, WIN XP, WIN NT, and WIN ME. MSTAT is available in English.
EASE OF USE
MSTAT is a very easy program to use. The manual uses sample data files to explain the operation of each program. User support is available via fax, email, or telephone.
Please don't hesitate to contact the MSTAT Office if you have further questions.
