- Review What's New in Aabel™ NG2, v5 x64.

- Efficient use of Kernel density estimate, which is widely used in data mining and pattern recognition, depends on computation of the optimal bandwidth of the kernel. While AMISE (Asymptotic Mean Integrated Squared Error) optimal bandwidth can provide the best estimation, it involves extensive and time-consuming computation.
- Gigawiz has developed a
**unique hybrid solver**for processing the data and estimating the corresponding AMISE optimal bandwidth by: - Computing the univariate density derivatives for each data point implementing the recommended methodology published by Raykar and Duraiswami (2005), followed by using the Sheather and Jones method (1991) for the actual bandwidth estimation.
- The Gigawiz hybrid solver has been stress tested using 10000 data sets, including both real world and simulated data.

Gaussian kernel density trace charts including:

- A graph type whose plotting involves processing the data and computing the AMISE optimal bandwidth (using the Gigawiz hybrid solver) while generating the resulting chart on the fly
- A graph type with the rule of thumb bandwidth selectors (i.e., Silverman's approach and percentage of sample range), for exploratory visualization of the effect of bandwidth on kernel density estimation
- Z-Score kernel density trace

- LOWESS is an outlier resistant, robust locally weighted regression and scatter smoothing, in which the fitted value of
*x*_{k}is the value of a polynomial fit to the data using weighted least squares, where the weight for (*x*_{i},*y*_{i}) is large if*x*_{i}is close to*x*_{k}and small if*x*_{i}is far from*x*_{k}. - The features and graph types include:
- Exploratory LOWESS Charts
- LOWESS Residual Dependence Graph
- Adding Weighted Confidence Interval (CI) to LOWESS Curves
- Using the LOWESS of Residuals as a Diagnostic Tool*

* The residual plot can provide information for choosing a reasonable value for the local smoothing width).

- One-way violin
- Two-way violin
- Three-way violin
- For interactive, exploratory visualization, you can choose one of the following options:
- Silverman's approach using alpha
- Silverman's approach using IQR
- Percentage of sample range (for this option, you can obtain the AMISE optimal bandwidth estimate (as well as the corresponding scaling factor) in the Stats Analyzer and use the output for providing the user-defined scaling factor)

A violin chart comprises a combination of box plot and density trace; violin chart types include:

Bandwidth Selector Options:

XY Scatter-line combination charts*****:

- With data objects connected along the sorted values of Y-axis
- With data objects connected along the sorted values of X-axis

***** Why Combining XY Scatter and Line Chart Properties?

- In an XY scatter chart, the data points represent groups of data objects that are plotted in the pipeline order (i.e., the order they are stored in the worksheet)
- In a line chart, the data points represent variables plotted along the sorted values of the Y- or X-axis.
- Combination graph types enable plotting a line chart in which the data points represent groups of data objects.

Multi-profile scatter-line Combination Charts:

- Trends of multiple X-variables plotted across the sorted values of a common Y-axis
- Trends of multiple Y-variables plotted across the sorted values of a common X-axis

- The newly added diagrams to specialized module of geochemical data provide flexibility for exploratory visualization of n-dimensional spidergrams generated from large data sets.
- Group-based n-dimensional REE or multi-elements diagrams include:
- Group-based spidergrams differentiated by data object markers and/or line attributes taken from the object marker color properties
- Group-based spidergrams differentiated by color bands

- This Open-GL utility is designed for:
- Subtracting a grid Z-values from another (e.g., generating a grid for an isopach map)
- Subtracting a grid Z-values from a user-defined XY plane
- Multiplying a grid Z-values by a constant, e.g., converting the Z-values from feet to meter
- Re-sampling the displayed grid by user-defined number of grid cells along the X and Y coordinates (e.g., for increasing resolution of a grid for volume or area calculations)
