RANDEC "RESINT" SE ("Standard") Edition - 5th degree equation, 100 experimental points (1st "RESINT" version standard for RSX-11M OS in the 1970s), 10 factors (dimensions), 20 members. There are no software upgrade options, sorry..  

RANDEC "RESINT" XE ("WinXP") Edition - 5th degree equation, 100 experimental points (1st "RESINT" version standard for RSX-11M OS in the 1970s), 10 factors (dimensions), 20 members: created for 32-bit Microsoft Windows XP or lower (32-bit Windows 2000, etc.) OS. Not for Microsoft Windows 64-bit operating systems. It may work on 32-bit higher than Windows XP operating systems (we successfully tested RESINT XE Software on 32-bit Windows Vista Home Premium version 6.0.6002 SP2, 32-bit Windows 7 Professional version 6.1.7601 SP1 and 32-bit Windows 8 Professional version 6.2.9200 SP0, but it didn't work on 32-bit Windows 10 any version), but it is at the user's own risk. It is possible to upgrade this program to "RESINT" SE version within one year from the date of purchase.

RANDEC "RESINT" UE ("University") Edition (not included in this item5th degree equation, 62 experimental points, factors (dimensions), 20 members. Includes two separate software on one CD: UE32 version,  optimized for  32-bit Windows and UE64 - optimized for 64-bit Windows. It is possible to upgrade these two software to "RESINT" both SE and XE versions within one year from the date of purchase. 

RANDEC "RESINT" LE ("Limited") Edition for USB (Universal Serial Bus) port (not included in this item5th degree equation, 13 experimental points, factors (dimensions), 12 members: due to the small number of points, more suitable for multi-factor non-linear regression functions demonstration than practical use - recommended for use of binary math and non-regression related other options. There are no software upgrade options, sorry..

Insights into history

The original code of “RESINT” was written in the 1970s in algorithmic high-level programming language FORTRAN IV. The author and developer of the program is the legendary computing specialist mathematician Vilnis Eglajs (1938-1993) [1]. The program successfully worked on the so popular and then very modern CM-4 (CM1403) mini computing machines (it is a copy  of the Digital Equipment Corporation PDP-11 computing system - cloned and manufactured in the former Eastern Bloc: USSR, Bulgaria and Hungary [2]) in the RSX-11M operating system.
At the beginning of the 1980s, the author of these lines, under the leadership of Vilnis Eglajs, recast the “RESINT” program so that it can be used for IBM-compatible, Intel 80x86 architecture-based computer in the Microsoft MS-DOS environment and it was used for scientific research at the August Kirchenstein Institute of Microbiology (Laboratory of Bioengineering and Biophysics), Latvian Academy of Sciences, resulting in the creation of several international publications [3, 4, 5, 6*, 7, 8, 9]. Then, in the 1990 s, the day light seen a version of “RESINT” for Microsoft's Windows 16-bit operating system  and later - for 32/64-bit one. Note that all “RESINT” commands (called mnemonics) are unique in the first three characters as for the RSX OS and the most critical parts of software code such as solution of a system of compatible linear equations AX=B, etc. are written in assembler language.

“RESINT” method

Regression equation quality indicators
Looking at the quality of the regression equation, two main indicators should be distinguished: accuracy and reliability. The precision of the regression equation is characterized by the mean square deviation (standard deviation) of the table data from the regression equation values at the corresponding points - the smaller the deviation, the higher the accuracy. By increasing the number of coefficients of the regression equation and thus making the equation more complicated, it can unlimitedly reduce the deviation of the output data from the equation. In a boundary case, when the number of coefficients of the equation coincides with the number of output data, it is possible to achieve a complete match of the output data with the values calculated using this regression equation. This regression equation is unlikely to have any meaning because it is unlikely to have good predictive properties: the values calculated in the intersections of the parameter area of the object from actual ones can vary unforgivably.
The reliability of the regression equation shall be characterized by the extent to which the deviations calculated at starting-points correspond to the inter-point deviations of the object's parameter room. It becomes understood that the less the number of regression equation coefficients, the higher the credibility of the equation. The good compliance of the regression equation with the output data at a small number of regression coefficients (relative to the set points) indicates that this harmony was achieved due to the structure of the regression equation itself, but not to the recovery of coefficients. Thus, the key indicators of the regression equation are contradictory: one improvement leads to a deterioration of the other.

Synthesis of the regression equation
In practice, the following task appears quite often: information about the object is given in the form of a table. Assuming that there is some relationship between the object's parameters and response (feedback), it is necessary to express this relationship mathematically - it is to create an object regression model based on the table data. Existing regression analysis methods, as a rule, require the existence of a regression equation with accuracy up to coefficients, the determination of which also constitutes the main computational work. However, in most cases the structure of the regression equation is unknown a priori. In this case, the use of regression analysis methods is difficult, especially the determined links between the parameters and feedback of the object. The proposed regression synthesis method does not require a priori knowledge of the regression equation structure. As previously mentioned, the approximation function is not predefined, but is synthesized in the process of processing information. The mathematical expression has the following form:

       m
Y = ⅀ [Bi * F(X)]
     i=1

where,

m - number of expression members;

Bi - coefficients;

F - elementary function;

X - vector of factors.

The elementary function is constructed as follows:

           NX
F(X)= П[Aj+Bj*Xj]*Lk,j
         J=1

where,

NX - number of factors;

Aj, Bj - coefficients;

Lk,j - integers that can accept both positive and negative values, including zero.

The algorithm provides both an automatic selection of the elementary function depending on the number of factors and the  results of the information analysis, as well as the analysis of the influence of individual factors and the exclusion of non-essential factors. For more detailed information, please see [10, 11].
