Data Mining Using Sas Enterprise Miner
An Overview of SAS Enterprise MinerThe following article is in regards to Enterprise Miner v. 3 which is available in SAS v Enterprise Miner an awesome product which SAS first introduced in version It consists of a variety of analytical tools to guide data mining analysis. 3 that’s available in SAS v Enterprise Miner an awesome creation that SAS first introduced in version It consists of a variety of analytical tools to aid data mining analysis. Data mining is definitely an analytical tool that’s utilized to solving critical business decisions by analyzing large amounts of data to be able to discover relationships and unknown patterns in the data. The Enterprise Miner data mining SEMMA methodology is specifically designed to handling enormous data sets in preparation to subsequent data analysis.
The purpose of the Sampling node is to execute various sampling techniques for the input data set. For binary-valued target variables to predict, there’s one more third step that is performed. From the results, the node displays the classification table to measure the classification performance of the first-stage model and the standard assessment statistics to evaluate the predictive performance of the second-stage modeling design. The node calculates two separate centrality measurements. The node gets the option of editing the target profile for categorical-valued target variables so as to assign prior probabilities to the categorical response levels that truly represent the appropriate degree of responses additionally to predetermined profit and price amounts for each target-specified decision consequences so as to maximum expected profit or minimize expected loss in the following Outliers summary statistical models.
The purpose of the Link Analysis node would be to visually display the relationship between your variables so as to define the characteristics between your variables. The DMDB procedure is used to produce the DMDB data mining data set. The nodes plot the data, generate a wide selection of analysis, identify important variables, or perform association analysis.
Explore Nodes. The WOE statistic measures the relative risk of the input grouping variable, that is, the logarithm difference of the response rate that is the main difference involving the proportion of the target nonevent and target event. For categorical-valued targets or stratified interval-valued targets, various numerical target-specified consequences can be predetermined in creating various business modeling scenarios that are made to maximize expected profit or minimize expected loss from the validation data set. Sample Nodes.
The Ease of Use to Enterprise MinerSAS Enterprise Miner is really a powerful new module introduced in version But, more to the point SAS Enterprise Miner is extremely easy application to find out and extremely an easy task to use. The procedure compiles and computes the metadata information of the input data set by the variable roles. The following are the remaining utility nodes available inside the SEMMA Enterprise Miner process flow diagram.
The Purpose of the Enterprise Miner NodesData Mining is a sequential procedure for Sampling, Exploring, Modifying, Modeling, and Assessing large numbers of data to discover trends, relationships, and unknown patterns in the data. For binary-valued target variables to predict, there is one more third step that is performed. For binary-valued target variables to predict, there’s an additional third step which is performed. The only parameter estimate that type of smoothing predictive model technique needs is the number of neighbors k. A subsequent table listing enables you to view the variables added and removed from your decision tree model.
