This course introduces programming techniques to craft and feature engineer meaningful inputs to improve predictive modeling performance. In addition, this course provides strategies to preemptively spot and avoid common pitfalls that compromise the integrity of the data being used to build a predictive model. This course relies heavily on SAS programming techniques to accomplish the desired objectives.

Skills Gained

  • extract data from a relational data table structure
  • define population qualifications and create a target sample
  • use feature engineering techniques to transform transactional data into meaningful inputs into a predictive model
  • transform low-, mid-, and high-cardinality categorical input variables into meaningful predictive modeling inputs
  • use ZIP codes and latitude/longitude points to calculate great-circle distance, driving distance, and estimated driving time
  • use Bayes' theorem to estimate meaningful predictive modeling inputs, impute missing observations, and partition the target sample into training and validation data sets for honest assessment of the predictive model.

Who Can Benefit

  • Analysts, data scientists, and IT professionals looking to craft better inputs to improve predictive modeling performance

Prerequisites

  • This course assumes some experience in both predictive modeling and SAS programming. Before attending this course, you should have
  • exposure to DATA step programming equivalent to SAS® Programming 1: Essentials
  • exposure to querying data in PROC SQL and building and deploying a predictive model
  • familiarity with the SAS macro language is helpful but not required
  • exposure to programming in SQL or the SQL procedure
  • familiarity with the analytical process of building predictive models and scoring new data.

The course and labs were well organized and performed flawlessly. They made sure that all the information was timely relayed to the students.

Great class, even better instructor!!!!! Standing ovation to Michael Staves!

Informative class with great instructure who was able to walk through the course material, answer all questions, and give great examples.

Great facility with good selection of drinks and small snacks. Equipment also worked flawlessly.

I thought this was a really cool experience. First time getting so much information crammed into two days.
