Data Science

Data science encompasses preparing data for analysis, including cleansing, aggregating, and manipulating the data to perform advanced data analysis.

Regression

01.

This Analysis is a form of predictive modelling technique which investigates the relationship between a dependent (target) and independent variable (s) (predictor)
