APPLICATION
PACKAGE FOR EXPERIMENTAL DATA PROCESSING Version
3.0 The
package is intended for processing results of various experiments and scientific
investigations by applied statistics and computational mathematics methods in
metrology, instrumentation manufacturing, ecology, medicine, physics, biology,
chemistry, economics, sociology and others. The
package is designed for a user unfamiliar with special sections of mathematics,
applied statistics and programming it is used for personal computers IBM PC
compatible. The
merits of the package are: statistical efficiency, user friendliness. The
package control is high-automated. The result presentation is most suitable for
the user (tables, plots, comments). The
contents and aspects of problems to solve are treated as a result of expert
guestioning with due regard for the features of the unprecedented problems
raised. Programs
contained in the package treat problems which can be confined to seven aspects. 1.
Computation of statistical numerical values includes: ·
computation of main numerical values of the phenomenon
under study; ·
computation of confidence intervals of main numerical
values; ·
computation and the histogram plotting; ·
computation of tolerance intervals; ·
checking of dispersion tolerance of variance estimation
in several observation groups; ·
checking of dispersion tolerance of mean arithmetic
group at different intragroup variance; ·
checking of dispersion tolerance of arithmetic mean by
Fisher method. 2.
Computation of dynamic characteristics includes: ·
identification of the first and second order equations
of transient processes under different initial conditions; ·
computation of pulse, transmission, transient and
amplitude-phase-freguency characteristics. 3.
Identification of functional dependences includes the dependence recovery:
·
y
= a×xb
(geometrical); ·
y
= a×ebx
(exponential); ·
y
= a×ln(b×x)
(logarithmic); ·
y
= a×xb×ecx
(geometric-exponential); ·
y
= a×(1
- e-bx)
(inverse-exponential); ·
y
= a + b×xc
(geometrical
with a free term); ·
y
= a + b×ecx
(exponential with a free term); ·
y
= (a+b×x)×ecx
(linear-exponential); ·
y
= h + (a+b×x)×ecx(linear-exponential
with a free term); ·
y
= a×xc×(1
- bx)d (product of geometrical); ·
y
= a×xc + b×xd
(sum of geometrical); ·
y
= a×ecx + b×edx
(sum of exponential); ·
y
= h + a×xc + b×xd
(sum of geometrical with a free term); ·
y
= h + a×ecx + b×edx
(sum of exponential with a free term); ·
y
= ecx×(a×cos(wx)
+ b×sin(wx))
(exponential-sine); ·
y
= h + ecx×(a×cos(wx)
+ b×sin(wx))
(exponential-sine with a free term); ·
(polynomial); ·
(geometric-polynomial); ·
(exponential-polynomial); ·
(logarithmic-polynomial); ·
(periodic); ·
(linear multiple regression). These
algorithms have been developed with regard to nonstationary variance within the
observation range considering nonlinearity factor. 4.
Identification of probability distribution densities includes: ·
estimation of unknown parameters of probability
distribution densities: normal, uniform, triangular, trapezoidal, antimodal I,
antimodal II, truncated Raileigh, chi-square, Student, binomial, Poisson; ·
identification of the above probability distribution
densities according to chi-square test; ·
identification of the above probability distribution
functions according to Kolmogoroff-Smirnoff and omega-square tests except for
Poisson and Bernoulli distribution functions; ·
checking of distribution normality at N<50. A pre-set power of these tests are ensured in the event of using estimations of unknown parameters of probability distributions defined according to the pre-set access on identifying distribution function by Kolmogoroff-Smirnoff and omega-square tests. 5.
Decision making application tasks include: ·
computation of density functions of suspended particle
sizes in liquid medium during dynamic sedimentation process at preset
theoretical and empirical distributions; ·
identification of M-dimensional
objects; ·
identification of two empirical distributions; ·
detection of intensity variation of the Poisson flow; ·
detection of intensity "spike" of the Poisson
flow; ·
checking of many simple hypothesis. 6.
Time series processing includes: ·
computation of multidimensional time series trends and
central random series; ·
determination of forecasted values of the temporal
series; ·
computation of one-dimensional distribution law of
momentary values of truncated realization of standardized random series; ·
computation of auto- and intercovariance (correlation)
functions and conduction of total correlation analysis; the latter includes the
following tasks: correlation factor, correlation factor homogeneity, correlation
indicator, partial correlation, multiplicity correlation factor; ·
computation of auto- and interspectral power densities; ·
trend checking of central random series for
stationarity; ·
checking of central random series for stationarity
according to the second moments; ·
checking of central random series for stationarity
using covariance matrix computation errors. 7. Generation of pseudo-random numbers and processes includes: ·
generation of pseudo-random numbers arranged according
to normal, uniform, triangular, trapezoidal, antimodal I, antimodal II,
truncated Raileigh, chi-square, Student, binomial, Poisson distribution laws; ·
generation of the Poisson flow. ·
generation of normally distributed random vectors; ·
generation of multidimensional normal Markoff
processes; Besides, the above application package runs service functions of input-output and initial data editing. There
is a standard access to each package program (detailed description is given in
the User Manual) and the user can insert each of them as a subroutine into a
package of his own. The
package workability has been tested in polar modes; the obtained results verify
algorithms stability and reliability as well as high accuracy of the values
computed. Language
options are provided for communication with the package.
There are two versions of the considered package for operational systems
MS DOS and WUNDOWS.
