R Studio is a powerful integrated development environment (IDE) for R, a programming language widely used for statistical computing and data analysis. While ANOVA (Analysis of Variance) is a common statistical method used in R, R Studio supports a wide range of other analyses as well. Here are some examples:
Regression Analysis
Regression analysis is used to model the relationship between a dependent variable and one or more independent variables. R provides several functions for performing regression analysis, including lm() for linear regression and glm() for generalized linear models. For example, to perform a simple linear regression:
# Create a datasetdata <- data.frame(x = rnorm(100), y = rnorm(100))# Fit a linear modelmodel <- lm(y ~ x, data = data)# View the summary of the modelsummary(model)Time Series Analysis
