Handling Missing Data in SAS and Proven Practices for Predictive Modeling

  • Date: August 6, 2020
  • Time: 11:00 a.m. – 1:00 p.m. EST
  • Location/Format: Webinar link

1. Handling Missing Data in SAS (slides/video)
What do you do when you have missing values in your data? In SAS we have many ways to manage missing values. In this session we cover what are missing values, why and when missing values occur and how to manage missing values. We discuss functions, procedures and how different products deal with missing values.

2. Proven Practices for Predictive Modeling(slides/video)
In our ongoing quest for “analytics excellence,” what are some of the strategies and tactics that we, as analytics practitioners, can consider not only for individual predictive modeling projects, but for increasing the value and importance of analytics in our organizations? This presentation will share some of the common strategies, attributes, processes and best practices of the most successful organizations. Best practices will include considerations for an overall analytics process as well as the discrete steps of building a predictive model, such as data preparation and sampling; input (variable) examination, selection and transformation; model selection and validation; and more.

    1. Learning Data Science with SAS® University Edition and JupyterLab (Brian Gaines)

    One of the interfaces included with SAS® University Edition is the popular JupyterLab interface. You can use this open-source interface to generate dynamic notebooks that easily incorporate SAS® code and results into documents such as course materials and analytical reports. The ability to seamlessly interweave code, results, narrative text, and mathematical formulas all into one document provides students with practical experience in creating reports and effectively communicating results. In addition, the use of an executable document facilitates collaboration and promotes reproducible research and analyses. After a brief overview of SAS University Edition, this paper describes JupyterLab, discusses examples of using it to learn data science with SAS, and provides tips. SAS University Edition is available at no charge to educators and learners for academic, noncommercial use and includes SAS® Studio, Base SAS®, SAS/STAT®, SAS/IML®, and some other analytical capabilities.

    2.  20 in 20: Quick Tips for SAS® Enterprise Guide® Users (Kelly Gray)

    Change is Good, or at Least Expected: Techniques for Visualizing Categorical Values Over Time

    Date and time: Friday, December 7, 2018 2:00 pm (Eastern Standard Time)

    Duration: 0.5 hour

    Description:

    Many techniques exist for showing how numeric values change over time. Bar charts, line charts, plots and many other graph types are all excellent ways to demonstrate how temperature, expenses and other measures increase and decrease over minutes, months or decades. On the other hand, such graphs don’t lend themselves to showing how and when categorical values such as grade, rating, score and status change over time. A simple combination of data manipulation, file merging, custom formatting and the Output Delivery System (ODS) can produce a wide range of useful, easy-to-interpret and effective reports. By using color, fonts, custom messages and other features to indicate a change in a data value, these reports make it easy to monitor progress or to detect when things are going in the wrong direction.

    Interpreting Black-Box Machine Learning Models Using Partial Dependence and Individual Conditional Expectation Plots

    Date and time: Friday, December 7, 2018 2:30 pm (Eastern Standard Time)

    Duration: 0.5 hour

    Description:

    One of the key questions a data scientist asks when interpreting a predictive model is “How do the model inputs work?” Variable importance rankings are helpful for identifying the strongest drivers, but these rankings provide no insight into the functional relationship between the drivers and the model’s predictions.

    Partial dependence (PD) and individual conditional expectation (ICE) plots are visual, model-agnostic techniques that depict the functional relationships between one or more input variables and the predictions of a black-box model. For example, a PD plot can show whether estimated car price increases linearly with horsepower or whether the relationship is another type, such as a step function, curvilinear, and so on. ICE plots enable data scientists to drill much deeper to explore individual differences and identify subgroups and interactions between model inputs.

    This paper shows how PD and ICE plots can be used to gain insight from and compare machine learning models, particularly so-called “black-box” algorithms such as random forest, neural network, and gradient boosting. It also discusses limitations of PD plots and offers recommendations about how to generate scalable plots for big data. The paper includes SAS® code for both types of plots. SASGF18

    Description:

    When a large and important project with a strict deadline hits your desk, it’s easy to revert to those tried-and-true SAS programming techniques that have been successful for you in the past. In fact, trying to learn new techniques at such a time may prove to be distracting and a waste of precious time. However, the lull after a project’s completion is the perfect time to reassess your approach and see if there are any new features added to the SAS arsenal since the last time you looked that could be of great use the next time around. Such a post-project post-mortem has provided me with the opportunity to learn about several new features which will prove to be hugely valuable as I rework this project for Round 2:

    • The presenv option and procedure
    • Fuzzy matching with the compged function
    • The ODS powerpoint statement
    • SAS Enterprise Guide enhancements including copying and pasting process flows and the macro variable viewer

    Encore: Introduction to Bayesian Analysis Using SAS/STAT®
    The use of Bayesian methods has become increasingly popular in modern statistical analysis, with applications in numerous scientific fields. In recent releases,SAS® has provided a wealth of tools for Bayesian analysis, with convenient access through several popular procedures,as well as the MCMC procedure, which is designed for general Bayesian modeling.This paper introduces the principles of Bayesian inference and reviews the steps in a Bayesian analysis.It then describes the built-in Bayesian capabilities provided in SAS/STAT, which became available for all platforms with SAS/STAT 9.3,with examples from the GENMOD and PHREG procedures. How to specify prior distributions,evaluate convergence diagnostics and interpret the posterior summary statistics are discussed.
