FAQ from ๐ Linear Regression Analysis with R?
Linear Regression Analysis is a statistical method used to study the relationship between a dependent variable and one or more independent variables. R is a programming language and software environment used for statistical analysis, data visualization, and machine learning. In linear regression analysis with R, the data is fitted to a linear model, and the coefficient values are estimated.
Linear Regression Analysis with R relies on several assumptions, including linearity, homoscedasticity, independence, normality, and absence of multicollinearity. These assumptions are necessary for the model to be valid and for the estimates to be accurate. Violations of these assumptions can lead to biased estimates and incorrect conclusions.
The results of linear regression analysis with R include the coefficient estimates, the R-squared value, and the p-values. The coefficient estimates represent the slope of the line or the change in the dependent variable associated with a one-unit increase in the independent variable. The R-squared value measures the percentage of variation in the dependent variable that is explained by the independent variable(s). The p-values indicate the statistical significance of the coefficient estimates, with values less than 0.05 indicating a significant effect.
