Statistical, Frequency, Linear and Nonlinear Analysis, and Forecasting
Powerhouse
Advanced Analytics Group has released Auguri 2.1, an integrated
Windows data exploration, analysis, and forecasting tool with emphasis
on nonlinear dynamical methods.
Auguri provides tools for the manipulation and analysis of data
throughout the process of predictive data mining. From data capture to
multivariate model design, and from the specification of solutions to
these models to their comparison and storage for later use, under a
powerful and intuitive graphical user interface.
Auguri will read data from most sources in ANSI or binary format, in
addition to its own format. It also supports drag and drop and copy
and paste operations to and from most popular editors and spreadsheet
programs. Future releases will include compliance with the Predictive
Model Markup Language (PMML), for models supported by our software,
and in interfaces to some of the most popular audio and image file
formats.
Auguri allows opening multiple document files simultaneously for
editing, inspection, charting, analysis or forecasting. It maps data
to worksheets, where a worksheet may consist of one or several sheets
containing additional data, models, solutions and reports.
Data may be edited freely and charted at will in most popular formats.
Not only can you instruct Auguri to plot your data in 3-dimensions,
but produce fully functional four-dimensional representations that can
be zoomed, rotated, or even animated.
The program also includes modern interpolation techniques for the
replacement of missing values, or for resampling of existing data
where additional information is desirable before continuing with
further analysis. In addition, Auguri provides several methods for the
automatic generation of constant and serial data in your documents.
Other than common statistical analysis methods such as ANOVA, test of
means and variances, histograms, IID tests and descriptive statistics
to the fourth moment, Auguri provides extensive nonlinear methods such
as generalized fractal dimensions, Poincare surface of sections,
maximal Lyapunov exponent, false nearest neighbors, space-time
separation plots, averaged mutual information, and phase portraits in
up to four-dimensions, among other.
It also provides tools for the analysis of signals and series in the
time and frequency domains, such as power spectrum estimation, Fourier
transforms, auto- and cross- covariance and correlation functions,
time-evolving statistics, and simultaneous solutions to linear
equations.
In addition, it includes several methods for the generation of random
numbers according to a chosen distribution, for sampling data from
existing populations, and for generating surrogate data, where
statistical and nonlinearity tests may be additionally carried.
Apart from standard operations such as scaling, normalization,
differencing, summation and operations between series, Auguri includes
a powerful functional expression parser. Simply type your functions
following a left to right order of evaluation as you would write them
in paper, and save them.
You can then apply these functions directly to selected ranges of data
through all of your open documents for as long as you want.
You can also design custom frequency filters that can be applied to
data in the time or frequency domain, separate your signals at the
chosen frequencies,
and allow for the specification of distinct models that can provide an
enhancement in the accuracy of your forecasts and systems
approximations.
It also includes methods for the empirical differentiation and
integration of data for instances when these quantities are preferable
or desirable in a model.
Auguri lists several methods for data smoothing and noise reduction.
Some of these methods are explicit, as in the case of moving averages,
frequency convolution, exponential smoothing and Savitzky-Golay.
Other methods will require the definition of an intermediate model
where an auto-regressive predictor, a locally constant predictor, or
an artificial neural network may be used as the discriminating
function. These methods provide a good set of choices for reducing
noise in instances where the preservation of the nonlinear dynamics of
chaotic attractors in state space is desirable.
Model Specification
With Auguri, system models may be specified with a few clicks of the
mouse. There is no need to expand data to specify complex, past and
multivariate dependencies. All data expansion takes place
automatically in memory, following your specifications, at prediction
or approximation time.
You can also save models and methods from any of your Auguri
documents, load them to other documents, or simply have them stored as
one of the possible solutions to a system for future references.
Solutions and Comparisons
Auguri allows the specification of concurrent solutions to defined
models, which can be tested in a simulation, compared, or individually
ran with new input data.
Select global or local methods guided by fast and precise state of the
art spatial databases, and variations thereof. Define solutions
according to your preferences and data characteristics. Compare auto-
regressive with local least squares methods side-by-side, or against
powerful multilayer feedforward
neural networks trained with innovative quasi-unsupervised learning
algorithms. Any and all is a choice. No restrictions apply.
Auguri v. 2.1 runs under Windows 98/Me/NT4/2000/XP/2003/Vista/2008.
Prices begin at $549.00 (US), with deeply-discounted academic
licenses.
