Copyediting has not been done yet so read at your own risk. Right now, we are primarily interested in the quality and organization of the content but are open to all of your thoughts. Code and data will be provided but not until everything has been finalized. Thanks for taking the time to read this. Changes since the Release All chapters are in the current release. The OkCupid data were reprocessed and there were slight changes in the results that affected Section 3. Chapter 2 has been reworked with more feature selection bits. The results for the linear projection methods in Section 6. Chapter 7 has also been substantially changed so that the Ames data are used instead of the stroke data. New figures were added to Chapter 8 to show how PCA can be used to find missing data patterns across rows and columns. The points that we were to make in this chapter were already added to various sections throughout the book. To reduce redundancy, the chapter was removed and a small section in Chapter 3 was added. In the HTML version, pages are sections now rather than chapters. This decreases the page load time.

Non-mathematical readers will appreciate the intuitive explanations of the techniques while an emphasis on problem-solving with real data across a wide variety of applications will aid practitioners who wish to extend their expertise. Readers should have knowledge of basic statistical ideas, such as correlation and linear regression analysis.

While the text is biased against complex equations, a mathematical background is needed for advanced topics. He has been applying predictive models in the pharmaceutical and diagnostic industries for over 15 years and is the author of a number of R packages.

Johnson has more than a decade of statistical consulting and predictive modeling experience in pharmaceutical research and development. His scholarly work centers on the application and development of statistical methodology and learning algorithms.

Applied Predictive Modeling covers the overall predictive modeling process, beginning with the crucial steps of data preprocessing, data splitting and foundations of model tuning.

The text then provides intuitive explanations. Skip to main content Skip to table of contents.

Pages Over—Fitting On the next slide. These procedures repeated split the training data into subsets used for modeling and performance evaluation. Examples are cross—validation in many varieties and the bootstrap. Fit the model on the remainder.

Create final model with entire training set and optimal parameter value. The Big Picture We think that resampling will give us honest estimates of future performance. Predict the hold—out samples.

One algorithm to select sub—models: Define sets of model parameter values to evaluate. K—Nearest Neighbors Tuning 0. Performance might not be the only consideration. Typical Process for Model Building Now that we know how to evaluate models on the training set.

Others might include: Linear Discriminant Analysis A simple model for fitting linear class boundaries to these data is linear discriminant analysis LDA..

Estimating Performance For Classification For classification models: Unconditional probabilities the positive—predictive values and negative—predictive values can be computed. Estimating Performance For Classification For 2—class classification models we might also be interested in: Estimating Performance For Classification For our example.

Increasing it makes it harder to be called PS! For two classes. The area under the ROC curve is a common metric of performance.

The ROC curve plots the sensitivity eg. Example ROC Curve 1. For example. The caret Package The caret package was developed to: First version on CRAN: The train Function The default resampling scheme is the bootstrap. To do this.. To use five repeats of 10—fold cross—validation. The train Function By classification.

For regression. For example: A custom performance function can be passed to train. The package has one that calculates the ROC curve. The classProbs option will also do this: R has many facilities for splitting computations up onto multiple cores or machines See Tierney et al On CRAN. The parallel technology must be registered with foreach prior to calling train: The test set estimate was 0.

Cross-Validated 10 fold.
