Covariance Matrix in R, Covariance is a measure of the degree to which two variables are linearly associated. We can measure how changes in one variable are associated with another variable. A covariance matrix...

partial correlation coefficient r, When we want to find the linear relationship between two variables, we often choose the Pearson correlation coefficient. But some cases we want to know the relationship between two variables...

z score how to find?, z-score provides how many standard deviations away a value is from the mean. We can use the following formula for z-score calculation. z-score = (x-μ)/σ x is a raw...

Intraclass Correlation Coefficient in R, ICC is used to determine if subjects can be rated reliably by different raters. In some kind of situation or studies with two or more raters or judges,  Intraclass...

Transition Plot in R, when we have quantitative data for change in time, visualization is straight forward but in the case of a categorical variable, it’s not as easy. In this article, we are...

Equality of Variances in R, in this article, we are describing variance comparison of 2 or more samples. There are different types of tests that can be utilized to assess the equality of variances....

In this article, we are going to compare pairs and ggpairs functions in R. 1. pairs() in R pairs() function mainly used to plot a scatter diagram corresponding to each data frame. Syntax: pairs(data)...
