There are two types of regression multilinear regression and simple linear regression. The simple linear regression is explained and is the same as above. Whereas multilinear regression can be denoted as Y = a + bX1 + cX2 + dX3 + ∈ Where, Y– Dependent variable X1, X2, X3– Independent...

With the results of the regression, the coefficient of the explanatory variable is the beta (the covariance divided by variance). Using Excel, pick a cell and enter the formula: "SLOPE" which represents the linear regression applied between the two variables; the first for the series of daily...
The process of minimizing RSS through least squares regression involves iteratively adjusting the parameters of the model. This is usually done until the optimal fit is achieved. For a simple linear regression model, this typically entails finding the slope and intercept of the line that best fits...
