Introduction

QLazDOE is a is a statistical software for designing and analyzing results of Designed Experiments (i.e. Design of Experiments, DOE).
It features DOE projects and solutions management, generator of designed experiments, factors and levels definition and integrated LazStats statistical software for statistical analysis of experimental results.
QLazDOE also contains rich collection of statistical tables.

Free License, Commercial License

You can start using QLazDOE for FREE, by using the free user account, as explained here: FREE QLazDOE application

There are no special restrictions with the free user account, except that you will share all your projects with another users.

If you wish your own separate user account, you can purchase commercial QLazDOE license here: Purchase QLazDOE license

Features

Projects and Solutions

The QLazDOE software enables users to define DOE projects and corresponding solutions. A project contains information about the problem case being subject of designed experiment, along with information about input factors and their corresponding levels.

You can create multiple solutions for a given project. Each solution corresponds to a separate designed experiment. You can choose design type and corresponding parameters for DOE generator and evaluate experimental results.

Definition of Factors and Levels

In DOE project you can easily define factors and levels in intuitive way via integrated spreadsheet software.

Generator of Designed Experiments

QLazDOE software provides generator of designed experiments. You can choose between various types of designed experiments and provide corresponding parameters for the DOE generator.

Analysis of Designed Experiment Results

Once you have collected experimental results, you can enter it into the previously generated spreadsheet and then perform various statistical analysis by using integrated LazStats Statistical software.

Included Free Software and Other Free Goodies

LazStats Statistical Software

LazStats is a great free and open-source statistical software, developed by mr. Bill Miller, the author of more widely known OpenStat software. OpenStat and LazStats share majority of their features, such as  a large variety of parametric, nonparametric, multivariate, measurement, statistical process control, financial and other procedures. One can also simulate a variety of data for tests, theoretical distributions, multivariate data, etc. Extensive list of supported features is listed here: LazStats/OpenStat Features

ezANOVA software

ezANOVA is another free program for analyzing data, integrated into the QLazDOE software. The author (Chris Rorden) developed this program for a statistics course purpose. More information on the author's site: https://people.cas.sc.edu/rorden/ezanova/index.html

Statistical Tables

QLazDOE Software contains multitude of various statistical tables integrated into the software, which you can use for DOE projects and any other statistical analysis purpose.
