Type II Error in R, we will discuss the concept of Errors in Hypothesis Testing, explore the different types of errors that may arise during this process, and learn how to calculate them. Hypothesis testing involves forming assumptions about a model or data set, which serve as the foundation for further analysis. The term ‘Error’… “Type II Error in R ..read more

Normal Distribution in R, also known as the Gaussian distribution, is a probability distribution that is frequently used in statistics and probability theory to describe continuous random variables. It has a bell-shaped curve, which is symmetrical around its peak, and has a single mode, mean, and median. In a normal distribution, the majority of the ..read more

Group By Minimum in R, the GROUP BY clause is used in combination with aggregate functions such as MIN(), MAX(), SUM() etc. to group rows that have the same value or similar values into summary rows. This allows you to perform calculations on the grouped data instead of on the entire dataset. The GROUP BY… “Group By Minimum in R ..read more

Group By Sum in R, the group_by() function is a powerful tool that allows you to split your data into groups based on specific variables or columns. Once the data is grouped, you can perform various operations on these groups, such as calculating summary statistics or aggregating values. One such operation is the sum() function,… “Group By Sum in R ..read more

Group by Mzximum In R programming, the group_by() function is used to group data based on one or more variables. The max() function, on the other hand, returns the maximum value in a vector or array. In this article, we will learn how to use the group_by() and max() functions together in R to find… “Group By Maximum in R ..read more
