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.

The self-study e-learning includes:

  • Annotatable course notes in PDF format.
  • Virtual Lab time to practice.

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 the SAS(R) Programming I: Essentials course.
  • Exposure to programming in SQL or the SQL procedure.
  • Exposure to querying data in PROC SQL and building and deploying a predictive model.
  • Familiarity with the analytical process of building predictive models and scoring new data.

What languages are used to deliver training?

Most courses are conducted in English, unless otherwise specified. Some courses will have the word "FRENCH" marked in red beside the scheduled date(s) indicating the language of instruction.

Great course, the labs were the best part of the course because it helped the material and information really sink in. We did have issues with one of the labs not being correct though

Very clean, great cafeteria and well sorted, very kind staff. The bathrooms have to be expanded as they might get crowded sometimes

Great resourses were available for us. The instructer was good and knowledgeable in this field.

Awesome training and trainers! Clear, straight to the point and extremely knowledgeable...

Exactly what we needed for our organization, at the right time, at the right price. We'll be back!
