WebLinear regression analysis involves examining the relationship between one independent and dependent variable. Statistically, the relationship between one independent variable (x) and a dependent variable (y) is expressed as: y= β 0 + β 1 x+ε. In this equation, β 0 is the y intercept and refers to the estimated value of y when x is equal to 0. WebStep 4: Analysing the regression by summary output. Summary Output. Multiple R: Here, the correlation coefficient is 0.99, which is very near 1, which means the linear relationship is very positive.
