Matrices | Covariance and correlation

Scatter matrix

In multivariate statistics and probability theory, the scatter matrix is a statistic that is used to make estimates of the covariance matrix, for instance of the multivariate normal distribution. (Wikipedia).

SCATTERPLOTS: Visualize Relationships Between Two Scale Variables (4-4)

Scatter Diagram (a.k.a. Scatterplot) is a graph used with correlation and regression. It summarizes the relationship between two quantitative variables. Trendline (a.k.a. Regression line) approximates the relationship between the two variables. A pair of scale variables, X and Y, are plott

How to Make a Scatter Plot Matrix in R

Scatter plot matrix is a plot that generates a grid of pairwise scatter plots for multiple numeric variables. Creating a scatter plot matrix can be a useful way to visually explore relationships between several numeric variables quickly. Code used in this code clip: library(tidyverse) li
