Estimation of Best Fitting Line
Estimation of model parameters is an essential part in regression analysis. We do that by using the Ordinary Least Squares method
Regression Analysis
Multiple Linear Regression Analysis with Categorical Predictors
Multiple Linear Regression Analysis with Categorical Predictors is done using Indicator Variables. We have to clearly analyze all possible models and select the best fitting model.
What are dummy variables in regression?
We use indicator variables when we have categorical variables in the Regression Equation. They are also known as Dummy Variables.
Multiple Linear Regression Example
Multiple Linear Regression helps us to make predictions using two or more predictor variables. Concept of Multicollinearity is also very important in Regression Analysis.
Linear Regression in MS Excel
Linear regression is a way of modeling variables to make predictions. Here we discuss how can we do a simple linear regression analysis using Microsoft Excel.
Simple Linear Regression
Simple Linear Regression is used to model the relationship between one predictor variable and one response variable. This is called ‘linear because the said relationship can be expressed in the form of the equation ‘y = mx + x”. And it is called ‘Simple’ because only one Predictor Variable is involved.
