The explanatory variable is the scale upon which the dependent or the response variable changes, for instance time. The constant represent the unwavering value in the regression equation, for instance, fixed costs.
An example of a multiple regression would be = mX + nZ, which is an equation to calculate profit for a company. The variable Y would be for profit margin, X for fixed costs and Z for variable costs. The values of m and n are the coefficients of X and Z respectively. The value of m would tell of the rate of change in slope attributable to X while n would show the rate of change of slope attributable to Z.
By assuming that the impacts of the other two components, which make 20% of the total sales are negligible, the error value increases significantly. In addition, since items B and C form part of the error, and will change with varying values of A, the model with be heteroscedastic, hence more difficult to use for the underlying trend in the data. Consequently, a linear model would make a poor fit for the data. Therefore, this use of regression analysis would be

Explain why or why not.
For the above model #1, the estimated intercept term is 698.933. Thus, when the average class size is equal to zero, the test score would equal to 698.933 since the error term or residuals will not

The author of the analysis presents certain results of the research. According to the study, additional 3 years of schooling will increase the number of female labor participation by (0.051285*3*100) = 15.3855 percentage points. Besides, the 10-year experience will reduce the number of female participation by (0.003083*10*100) =3.083 percentage points.
