How to Analyze Heteroskedasticity for Time Series Data in Multiple Linear Regression and Its Interpretation

By Kanda Data / Date Dec 14.2024 / Category Data Analysis in R

The heteroskedasticity test is one of the assumption tests in the Ordinary Least Squares (OLS) linear regression method, aimed at ensuring that the residual variance remains constant. If the multiple linear regression equation being tested shows non-constant residual variance, this is referred to as heteroskedasticity.

Testing and Interpreting Homoscedasticity in Simple Linear Regression with R Studio

By Kanda Data / Date Dec 16.2023

Homoscedasticity is a crucial assumption in ordinary least square (OLS) linear regression analysis. This assumption refers to the consistent variability of regression residuals across all predictor values. Homoscedasticity assumes that the spread of residual regression errors remains relatively constant along the regression line.

Simple Linear Regression Analysis Using R Studio and How to Interpret It

By Kanda Data / Date Dec 04.2023

In the real world, accurate decisions need to be based on a deep understanding of data. One tool for processing and elaborating data is simple linear regression analysis. Simple linear regression analysis allows us to read patterns among scattered data points. A correct understanding of regression analysis gives us the power to make more accurate decisions and minimize uncertainty.

How to Test for Normality in Linear Regression Analysis Using R Studio

By Kanda Data / Date Nov 21.2023

Testing for normality in linear regression analysis is a crucial part of inferential method assumptions, requiring regression residuals to be normally distributed. Residuals are the differences between observed values and those predicted by the linear regression model.
