especially if the data sample is large. However, there are many software tools that can help you save time when calculating the coefficient. TheCORREL functionin Excel is one of the easiest ways to quickly calc
I am new to matlab and I'm working on a problem with training data X and target data t. The target t is either 1 or 0 denoting which class the rows of X belong to. X is a 179x2 matrix, and I'm supposed to find the "within group correlation" between two variables x1 and x2...

The statistical relationship between two variables is referred to as their correlation. A correlation could be presented in different ways: Positive Correlation: both variables change in the same direction. Neutral Correlation: No relationship in the change of the variables. Negative Correlation: ...

Correlation is a term that is a measure of the strength of a linear relationship between two quantitative variables (e.g., height, weight). This post will define positive and negative correlations, illustrated with examples and explanations of how to measure correlation. Finally, some pitfalls ...
A correlation coefficient, r, is a number between -1 and 1 to measure the relationship between two variables. The sign of r (positive or negative) indicates the direction. If it is positive, both variables increase or decrease together. If it is negative, one variable increases while another...
What is the Correlation Coefficient? The correlation coefficient of a data set is a statistical number that tells how strongly two variables are related to each other. It can be said that it is the percentage of the relation between two variables (x and y). It can't be greater than 100...
A correlation matrix is a table showing correlation coefficients between variables. Each cell in the table shows the correlation between two variables. A correlation matrix is used to summarize data, as input into a more advanced analysis, and as a diagnostic for advanced analyses. ...
