Solving a Linear Optimization problem using R

Introduction to Linear Optimization Optimization is a technique for finding out the best possible solution for a given problem for all the possible solutions. Optimization uses a rigorous mathematical model to find out the most efficient solution to the given problem. To start with an optimization problem, it is important to first identify an objective. An objective is a quantitative measure…

Linear Regression in R and its interpretation

Linear Regression Linear regression modeling is one of the most frequently used supervised learning technique. It is useful when the dependent variable is continuous (ratio or interval scale) and there exists a linear relationship between the dependent and independent variables. This post is a quick guide to perform linear regression in R and how to interpret the model results. In the…
