R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...

R-squared coefficients range from 0 to 1 and can also be expressed as percentages in a scale of 1% to 100%. A measure of 70% or more means that the behavior of the dependent variable is highly explained by the behavior of the independent variable being studied. Additionally, the coefficien...
The Pearson coefficient shows correlation, not causation. English mathematician and statistician Karl Pearson is credited for developing many statistical techniques, including the Pearson coefficient, the chi-squared test, p-value, and linear regression. Benefits of the Pearson Coefficient For an investor ...
How many data points and how large an R-squared value is essential for Arrhenius plots? Arrhenius plots estimate the apparent activation energy (Ea) of catalytic reactions. The R-squared value (r2) often accompanies the Arrhenius plot to suppo......
