Panel data, also known as longitudinal data, involves collecting observations on multiple entities (such as firms, individuals, or countries) over multiple time periods. Researchers often use fixed effects, which can be in the form of time dummies or industry dummies, to account for various sources of data variation. In this article, we will test the […]
In this article we will discuss t-test tactics in R thoroughly. T-test is a statistical tool used to compare the averages (mean) of two groups or samples and determines whether there is a statistically significant difference between them. T-test are especially helpful when working with small sample sizes (usually less than 30 observations per group).
Panel data regression, also known as longitudinal or cross-sectional time-series data analysis, is a powerful statistical method for examining how independent variables affect a dependent variable over both time and individual units (cross-sectional units). For more details about panel data see Theory of Panel Data In this tutorial, we will walk through the process of

Just like a CSV file can be imported and exported in R, we can also import and export an Excel file. If we have data in Excel format, we cannot use read.csv or write.csv functions to import or export it. Instead, we use other functions like read_excel and write_excel for that purpose. We start by
