Determine the significance of a mediation effect in R, the Sobel test is a statistical test to determine the significance of a mediation effect. A mediation effect occurs when the relationship between two variables (X and Y) is explained by the presence of a third variable (M). The Sobel test is used to determine whether…

How to Display Percentages on Histogram in R, A histogram is one of the most commonly used charts to illustrate the distribution of a dataset. Histograms plot the frequency of observations of a variable using non-overlapping intervals, also called bin widths, on the horizontal axis and the count or percentage frequency on the vertical axis….
Pattern mining analysis in R is an essential technique for uncovering relationships and patterns in large datasets. It is a type of data mining that looks for patterns and connections within data sets to identify associations and relationships of association rules. Pattern mining analysis is often used in market basket analysis, where it is used…
Computational Gastronomy for Data Science, Computational gastronomy is an emerging field that combines the principles of data science and gastronomy to understand and analyze cooking processes, recipes, and food consumption patterns. The goal is to discover new flavor and texture combinations, understand the science behind culinary traditions, and refine recipes through data analysis. The discipline…
Error attempt to apply non function in r, The “attempt to apply non-function” error message in R usually appears when we try to use a variable as a function or call a non-function object as if it were a function. In other words, R expects a function to be called, but instead, it receives a…
Error-list-object-cannot-be-coerced-to-type-double-2 in R, a list is a commonly used data structure that can hold different types of objects such as vectors, data frames, matrices, and even other lists. However, in some cases, we may want to convert a list object into a different type of object, such as a numeric or character vector, or a…

Aggregate daily data to monthly and yearly in R, Data aggregation is an important step in data analysis that involves summarizing data in a coarser temporal resolution for ease of analysis and visualization. For example, daily data can be aggregated into monthly or yearly data, allowing for better identification of trends and patterns. In this…

Apply Central Limit Theorem in R, The Central Limit Theorem is a fundamental concept in statistics that states that the sample means of independent and identically distributed random variables, with a large enough sample size, will follow a normal distribution. This theorem has significant implications for statistical analysis as it allows us to apply statistical…
