The least squares module or the simple linear regression module in QM for Windows can be used to develop a linear trend line forecast. Using the least squares module, the solution summary for the linear trend line forecast we developed for PM Computer Services is shown in Exhibit 15.7.orrelation. Correlation in a linear regression equation is a measure of the strength of the relationship between the independent and dependent variables. The formula for the correlation coefficient is. Correlation is a measure of the strength of the relationship between independent and dependent variables.
