WebFor example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables. It is important to note that there may be a non-linear association between two ... WebDec 19, 2024 · Linear regression equation (Image by Author) The linear regression has two regression coefficients as follows. The parameter beta_0 is known as an intercept; The parameter beta_1, beta_2, …, beta_k are known as the slope. If a value close to 0, it indicates that there is no relationship between the dependent and independent variables.
