Application of Variable Selection Techniques to Identify Significant Predictor Variables

This project is designed to equip the learners with Data visualization, Feature engineering and Regression techniques.

Application of Variable Selection Techniques to Identify the Significant Predictor Variable
  • 2 bar graph
    Difficulty: Intermediate

    Foundational knowledge or experience in statistics or analytics is recommended.

  • Asset 1
    Duration: Approximately 2 hours

Case Overview

  • Only a small portion of the dataset’s variables can be used to build a machine learning model; the others are either repetitive or irrelevant. In order to remove the unnecessary features from the data, it is crucial to discover and choose the most appropriate features from the data, which is accomplished with the aid of variable selection in machine learning.
  • Airfares are determined by a variety of factors, and as a result, they fluctuate significantly, with each airline using its own pricing algorithm. A travel business wishes to find new solutions to ascertain the most critical elements influencing airfares and forecast airfares for several popular itineraries.
  • Travel agencies build predictive models for forecasting fares, though how does one choose the factors with most explaining power.
  • Learn how different variable selection techniques can be used by travel agencies for maximizing sales.

Case Context

  • It is always important to keep the data that adds value to the analysis & remove the insignificant ones.
  • Variable selection is intended to select the best subset of predictors.
  • The aim is to construct a model that predicts well or explains the relationships in the data.

  • The data is summarized, and various visualization techniques were applied.
  • A variable is correlated with another variable(s), such Multicollinear variables are removed using the Variance Inflation Factor (VIF).
  • By selecting the variables which tends to have an influence on the Airfare, we fit 3 different regression models on the data.

  • Measuring the predictor relation, and response predictor relation is important to recognize the relationship exist.Multicollinear variables can be identified and removed from model building.

    Selecting highly significant variables can improve the overall predictive capacity of machine learning models.

How it Works

Learn new skills that will boost your career by enrolling in courses across data analytics, data science, ML and AI. These courses will utilize readings, videos, quizzes, data cases, and even coding exercises to teach you skills and concepts in a way that will solidify your new knowledge for hands-on application.

With our hands-on projects, you will take your newly learned skills along with our 750+ low-code/no-code functions and embedded coding console to complete milestone-based projects. Once completed, you will have effectively applied new skills and concepts to real-world data cases that can be translated directly into your career.

Complete assessments and track your progress in real-time to benchmark your proficiency in relation to key functional areas. As you progress through your courses, our patented platform will utilize ML and AI to record and analyze your inputs and output to provide active feedback and recommendations that will help you learn more effectively than the standard Letter Grade system used today.

Complete courses to earn sharable certificates and badges. These awarded items will be look great in your portfolio as you showcase your skills and project experience to employers and colleagues.
