Coefficient of relationship genetics formula
WebApr 22, 2024 · Formula 1: Using the correlation coefficient Formula 1: Where r = Pearson correlation coefficient Example: Calculating R ² using the correlation coefficient You are studying the relationship between heart rate and age in children, and you find that the two variables have a negative Pearson correlation: WebThe closer the coefficient is to either −1 or 1, the stronger the correlation between the variables. If the variables are independent, Pearson's correlation coefficient is 0, but the converse is not true because the correlation coefficient detects only linear dependencies between two variables.
