Korrelationmatrix
A correlation matrix is a table that displays the correlation coefficients between variables in a dataset. It is a square matrix where the cell at the i-th row and j-th column contains the correlation coefficient between the i-th and j-th variables. The diagonal elements of the matrix are always 1, as they represent the correlation of a variable with itself. The off-diagonal elements range from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.
Correlation matrices are commonly used in statistics and data analysis to understand the relationships between variables.
To create a correlation matrix, one first calculates the correlation coefficient for each pair of variables
In summary, a correlation matrix is a valuable tool in data analysis for understanding the relationships between
