WebRSQ: Calculates the square of r, the Pearson product-moment correlation coefficient of a dataset. INTERCEPT: Calculates the y-value at which the line resulting from linear regression of a dataset will intersect the y-axis (x=0). FORECAST: Calculates the expected y-value for a specified x based on a linear regression of a dataset. WebPearson Correlation Formula. The name correlation suggests the relationship between two variables as their Co-relation. The correlation coefficient is the measurement of correlation. To see how the two sets of data are connected, we make use of this formula.
