The original method of data analysis

What is the main distinctive feature of DALSolution?

Answer. The new technology of data processing and analysis based on the analysis of rules.

What are the differences between DALSolution and other analytical packages?

Answer.

Unified methodology of analysis instead of dozens of methods.

In contrast to packages containing dozens of methods, DALSolution offers a thorough and convenient methodology for solving the main tasks of descriptive analysis:

Task 1. “Analysis of relationships between categories or values”
Task 2. “Construction of new categories or values from existing ones”
DALSolution is the only package on the market that solves these tasks with Determinacy Analysis (DA), an original system of methods for the analysis of rules.

Solving a problem, not applying a method.

All tasks resulting in the explanation, forecast and discovery of significant factors can be reduced to tasks of rules analysis. The mathematical theory of rules (DA) for the analysis of relationships solves widespread practical problems in a simple and fundamental manner. It does not have the drawbacks of factor analysis and classic approaches, and DALSolution does not force you to use a variety of disjoint analytical methods.

Natural language is used in communication between the user and the software.

DALSolution encourages the use of everyday language in solving data processing and analysis tasks. This is accomplished with the original technology of manipulating Dictionaries of variables. The use of Dictionaries provides for a non-technical style of working with data, is user-friendly and simple to master.

The methods of analysis of rules are applicable in any situation.

The methods implemented in DALSolution have unlimited applications. When common statistical methods are properly applied, the analysis of rules techniques lead to comparable results, different only in representation. When common statistical approaches are not applicable, the analysis of rules turns out to be the only reliable way to develop explanatory or forecasting rules.

Results are understandable.

The software implements original mathematical models. However, it does not contain mathematical “black boxes”. Results obtained with DALSolution are easily interpreted and understood.

DALSolution does not violate language norms.

A norm of natural language is that a general statement can be explicitly connected with the particular cases used to derive the statement. Compare the following two statements:

“15% of surveyed women and 90% of surveyed men are able to lift a weight of 50 kilograms.”, and
“The correlation coefficient between sex and ability to lift weights is 0.62.”

The first statement conforms to the norm expressed above, preserving the link to images of particular men and women who either can or cannot lift weights. In the second statement, this connection is lost, and the norm of natural language is violated. In this sense, the majority of statistical methods do violate the norms of natural language.

The principles built into the foundation of DALSolution do not contradict the language norms. Both technical and non-technical specialists can use DALSolution with equal ease.

The package is equally accessible to novices and experts of practical data analysis.

Qualitative and quantitative factors somehow influence the phenomena that happen. But how? If you really need to figure this out, then DALSolution is indispensable to you.
