Regression in data science is crucial for understanding the relationships between variables and making predictions. At its core, regression is a statistical technique that enables us to understand how one or more independent variables influence an outcome or dependent variable. Read the following sections...

Regression inmachine learningis a technique used to capture the relationships between independent and dependent variables, with the main purpose of predicting an outcome. It involves training a set ofalgorithmsto reveal patterns that characterize the distribution of each data point. With patterns identifi...
A multiple linear regression model isyi=β0+β1Xi1+β2Xi2+⋯+βpXip+εi, i=1,⋯,n, wheren is the number of observations. yi is the ith response. βk is the kth coefficient, where β0 is the constant term in the model. Sometimes, design matrices might include information ab...
The test environment is fully set up and mirrors production. Test data is available and ready to be used. Regression test cases are prepared and prioritized. Exit points, on the other hand, defines when testing can be considered complete. This ensures that sufficient testing has been done to ...
An ETL pipeline is a traditional type of data pipeline which converts raw data to match the target system via three steps: extract, transform and load. Data is transformed in a staging area before it is loaded into the target repository (typically a data warehouse). This allows for fast an...
