Introduction to Data Mining
Definition:
Data mining (or Knowledge Discovery) refers to the process of analyzing a give data set from different precepts and scenarios in order to discover patterns in the given data set
Data mining is becoming an increasingly important tool to transform data into information. This information can help reveal the hidden trends about products, customer, market, employees and other factors critical for the success of a company.
Data mining It is commonly used in a wide range of profiling practices, such as marketing, surveillance, fraud detection and scientific discovery, machine learning, Biotechnology etc.

Introduction to XLMiner
XLMiner™ is a comprehensive data mining add-in for Excel.
XLMiner can be used to mine data available in Excel worksheets.
It includes capabilities that allow a miner to work with partitioning, neural networks, classification and regression trees, association rules, nearest neighbors, etc.
With is ease of use and learning , XLMiner serves to be the perfect candidate tool to wet your feet in Data Mining as a novice miner.

Introduction to XLMiner
XLMiner can work with large data sets which may exceed the limits in Excel. A standard procedure is to sample data from a larger database, bring it into Excel to fit a model, and, in the case of supervised learning routines, score output back out to the database. In the standard edition of XLMiner, this feature is supported for Oracle, SQL Server and Access databases.
XLMiner is available in 4 versions:
Demo edition (functional 30-day web download)
Education edition
Professional edition
Academic Research edition
The Demo edition and Educational Editions support only Excel.

How to get XLMiner
The 30 day demo edition can be downloaded for free from the company website:
http://www.resample.com/xlminer/index.shtml
System Requirements:
Once the download is complete , an installer wizard is opened. Follow the instruction in the wizard, and on completion open Excel and click on the “Add-Ins” tab to use XLMiner or double click on the XLMiner desktop icon.

Brief description of the features of XLMiner: Partition Data
Using this tool we can divide the data sets into mutually exclusive partitions i.e. partitions that do not overlap.
Generally we partition the data set into 3 parts-
Training Set.
Validation set.
Test set.
We can create the partitions in two ways:
Standard Partition: A default 60:40 Training :Validation set ratio partition is set as default, or we may specify it .
Oversampling: Used when we want a particular data item which is important but under-represented in the set.

Data Utilities
The XLMiner provides the user with a host of Data Utilities at his disposal. They are:
The different Data Utilities that XLMiner Provides are:-
Sample from Worksheet/Database.
Simple Random sample.
Stratified Sampling.
Missing Data handling.
Bin Continuous Data.
Transform Categorical Data .

Classification
XLMiner provides a host of classification tools that use efficient classification algorithms to classify data.
Discriminant Analysis.
Logistic Regression.
Classification/Decision tree.
Naïve Bayes.
Neural network.
K-nearest neighbor.

Affinity (Association Rules)
Affinity or Association rules means finding interesting correlations or associations between different data items in the data set. Usually used for market basket analysis which gives the user a list of product recommendations based on the products he purchases.

Prediction
XLMiner provides tools that can be used to predict the values of data items in the data sets using different prediction algorithms.
Different prediction techniques are:
Multiple Linear Regression
K-nearest neighbor
Regression Tree
Neural Network

Time Series
Time series analysis is done to understand the distribution of data points over time and such an analysis is useful for the purpose of prediction – for example, the future trends over time can be predicted by information extracted from the past performance
Exploratory techniques are:
ACF (Auto correlation function)
PACF (Partial auto correlation function)
Soothing and Forecasting

Data reduction and Exploration
Data exploration is an approach to analyze data for the purpose of formulating hypothesis that can be worth testing. XLMiner provides different tools for this purpose
Principal Component Analysis
K-Means Clustering
Hierarchical Clustering

Charts
XLMiner provides a charting feature too to chalk up graphs and charts for a more visual and convenient representation of data. Different chart tools are:
Histogram.
Box Plot.
Matrix Plot.
