## What Is DataMinerXL?

DataMinerXL is a Microsoft Excel add-in which provides a collection of functions for building predictive models. You can call on these functions directly from a spreadsheet and they return the modeling results directly back to it. Both researchers and practitioners in a wide variety of statistics and data mining fields will find this software valuable.

With this software, you can do the following:

- Perform basic statistical analysis
- Analyze importance of variables using weight of evidence (WOE) transformation
- Perform principal component analysis and factor analysis
- Build linear regression models
- Build partial least square regression models
- Build logistic regression models
- Perform time-series analysis
- Estimate the parameters of GARCH model
- Perform Holt-Winters exponential smoothing
- Perform the Hodrick-Prescott filter for a time-series
- Perform linear discriminant analysis and quadratic discriminant analysis
- Estimate the parameters of a stochastic process: normal (Guassian) process, lognormal process, and shifted lognormal process
- Build naive Bayes classifier models
- Build decision tree-based models
- Perform correspondence analysis
- Perform clustering and segmentation analysis
- Build neural network models
- Build support vector machine (SVM) models
- Score a population given a model
- Evaluate model performance given a model
- Save scoring code given a model
- Solve linear programming, quadratic programming, and linear complementarity programming problems
- Solve nonlinear least squares problems using the Levenberg-Marquardt algorithm
- Solve minimization problems using differential evolution solver
- Solve a transportation problem, assignment problem, minimum cost network flow problem, maximum network flow problem, and shortest path problem
- Perform a variety of matrix operations
- Perform fast Fourier transform and inverse fast Fourier transform
- Perform numerical integration by Gaussian quadrature
- Save spreadsheet tables into files and load data into spreadsheets from files
- Sort data files
- Save a table in a spreadsheet into a file with TEX format
