**RegPack
(RegComp) Installation and Related Notes:**

**1. **__Copyright
and Conditions-__**The component "RegComp.dcu"
has been copyrighted with the US Copyright Office (US Library of
Congress, 11/98). The author gives you, "the user",
permission to incorporate the component into a commercially-distributed
or non commercially-distributed software application so long as
this software application is in the form of a compiled executable
file (a ".exe" file). The author reserves the rights to
any and all other uses. The component may not be decompiled,
reverse-engineered, nor modified in any other form without the
author's express written permission.**

**2. **** Disclaimer-**While the author has put forth a
good faith effort to ensure that the component herein functions
without error and imposes no deleterious side-effects upon the
user's compiled computer code, this software component is
provided "AS IS" and the author (Fred J. Edberg)
accepts no liability nor responsibility for the performance of
the component itself or for any effects intended or otherwise
upon the final program which the component is included into.

**3. **__Compatibility__**-**The component has been
tested in both the Delphi 2 and Delphi 3 environments and appears
to have no problem in either. The component is NOT compatible
with the 16-bit Delphi 1.0 environment (this is due to the use of
certain primitive numerical data types and such). I have not
tested it in Delphi 4.0. But, this zipped installation archive
includes both the D3 package and related files, as well as, the 'bare'
compiled component ('regcomp.dcu'). Should you have any
difficulties with the package installation (D3 and D4), then you
can always choose to install the single component ('regcomp.dcu)
into an existing package and this should work just fine as a
"fallback" strategy**.**

**4. **** Functionality-**This component is a by-product of
some code I developed while in graduate school and which I had
revised since that time. The statistical functions included
within primarily focus upon MULTIVARIATE (MV) PARAMETRIC and
REGRESSION related tasks. Does it do everything for everyone?
Well, no-but here's a brief, but partial, list:

**Regression:
**

Regression summary parameters (Mean Square Regression, Mean Square Error, Model F Statistic, Deg. of Freedom, Sum Squares Total, Sum Squares Regression, Sum Squares Error, etc.)

Predicted Values of Y

Residuals-Raw, standardized, studentized

Diagnostics-Cook's Distances, Leverages

Confidence Intervals on Predicted Values of Y-At alpha = 0.99, 0.95, and 0.90.

Stepwise Procedure(s)-Variables added one-at-a-time (1.to..n) and (n..downto..1), and all-possible-combinations [up to 8 predictor variables]).

**Measures of
Covariance/Correlation:**

Predictor Variables Covariance Matrix

Predictor Variables Correlation Matrix

Predictor Variables Means-Differences Matrix

Paired Predictor Variable(s) on Dependent Variable Summaries

**Statistical
Distance and Separability Measures:**

Distance Measures of a single data point to the [parametric, in most cases] 'center' of a distribution: including the "L" distance, Euclidean, Normalized Euclidean, Mahalanobis, and Maximum Likelihood.

Separability Measures: Average Normal Distance, and Divergence

**Variable
Transformation Functions:**

Standardized Scores (z's)

Centered Scores

Normalized Scores

**Univariate
Variable Summary Statistics:**

Mean

Min

Max

Variance

Std. Dev.

Coefficient of Variation

Kurtosis

Skewness

Median

Range

**Advanced
Variables Analysis:**

Eigenvalues

Condition Indexes (for each component)

Eigenvectors Matrix

Factors Matrix

Factors Loadings Matrix

Principal Component Scores (from covariances)

**Supporting
Functions/Misc.:**

Statistical Tables: t, z, F (partial)

Lower-level functions for vector and matrix manipulations and summaries

**5. **** Contact
Info/Shareware/Souce Availability-**A shareware
version is available which contains identical functionality but
with the suppression of the "nag" dialog shown both at
design-time and at run-time. The shareware component is US $20.00
and is returned via email (only). The component is sent within
one day upon receipt of the secured payment.

The full source code is available. This includes six files (1 main component [.pas], and 5 include files [.inc]) and contain about 8000 lines of code total. The cost is US $100.00 and it also is returned via email (only). Similar payment and transfer procedures are used in this case as well.
