Introduction to Predictive and Specialized Modeling
Overview of Modeling Techniques
Predictive and Specialized Modeling provides details about more technical modeling techniques, such as Response Screening, Partitioning, and Neural Networks.
The Modeling Utilities assist in the data cleaning and pre-processing stages of data analysis. Each utility has exploratory tools to give you a more thorough understanding of your data. See Chapter 3, “Modeling Utilities”.
The Neural platform implements a fully connected multi-layer perceptron with one or two layers. Use neural networks to predict one or more response variables using a flexible function of the input variables. See Chapter 4, “Neural Networks”.
The Partition platform recursively partitions data according to a relationship between the X and Y values, creating a decision tree of partitions. See Chapter 5, “Partition Models”.
Image shown hereThe Bootstrap Forest platform enables you to fit an ensemble model by averaging many decision trees each of which is fit to a random subset of the training data. See Chapter 6, “Bootstrap Forest”.
Image shown hereThe Boosted Tree platform produces an additive decision tree model that is composed of many smaller decision trees that are constructed in layers. The tree in each layer consists of a small number of splits, typically five or fewer. Each layer is fit using the recursive fitting methodology. See Chapter 7, “Boosted Tree”.
Image shown hereThe K Nearest Neighbors platform predicts a response value for a given observation using the responses of the observations in that observation’s local neighborhood. It can be used with a categorical response for classification and with a continuous response for prediction. See Chapter 8, “K Nearest Neighbors”.
Image shown hereThe Naive Bayes platform classifies observations into groups that are defined by the levels of a categorical response variable. The variables (or factors) that are used for classification are often called features in the data mining literature. See Chapter 9, “Naive Bayes”.
Image shown here The Model Comparison platform lets you compare the predictive ability of different models. Measures of fit are provided for each model along with overlaid diagnostic plots. See Chapter 10, “Model Comparison”.
Image shown hereThe Formula Depot platform enables you to organize, compare, profile, and score models for deployment. For model exploration work, you can use the Formula Depot to store candidate models outside of your JMP data table. See Chapter 11, “Formula Depot”.
The Fit Curve platform provides predefined models, such as polynomial, logistic, Gompertz, exponential, peak, and pharmacokinetic models. Compare different groups or subjects using a variety of analytical and graphical techniques. See Chapter 12, “Fit Curve”.
The Nonlinear platform lets you fit custom nonlinear models, which include a model formula and parameters to be estimated. See Chapter 13, “Nonlinear Regression”.
The Gaussian Process platform models the relationship between a continuous response and one or more continuous predictors. These models are common in areas like computer simulation experiments, such as the output of finite element codes, and they often perfectly interpolate the data. See Chapter 14, “Gaussian Process”.
The Time Series platform lets you explore, analyze, and forecast univariate time series. See Chapter 15, “Time Series Analysis”.
The Matched Pairs platform compares the means between two or more correlated variables and assesses the differences. See Chapter 16, “Matched Pairs Analysis”.
The Response Screening platform automates the process of conducting tests across a large number of responses. Your test results and summary statistics are presented in data tables, rather than reports, to enable data exploration. See Chapter 17, “Response Screening”.
The Process Screening platform enables you to explore a large number of processes across time. The platform calculates control-chart, process stability, and process capability metrics, and detects large process shifts. See Chapter 18, “Process Screening”.
The Predictor Screening platform enables you to screen a data set for significant predictors. See Chapter 19, “Predictor Screening”.
Image shown hereThe Association Analysis platform enables you to identify items that have an affinity for each other. It is frequently used to analyze transactional data (also called market baskets) to identify items that often appear together in transactions. See Chapter 20, “Association Analysis”
