Prove Math (Without Regression as a Proof)
I can prove this problem using regression, but I don't have an equation for it. Please help, thanks! a.) Suppose you multiply all X1 values by 2 in an equation with one independent variable (X1) and a constant. What will be the effect of this rescaling, if any, on the coefficients (SYMBOL1 and SYMBOL2) and their standard erro ...continues

Calculate the Operating Leverage
I calculated the break-even points for three products - keyboard, software, soundcard - and I am confident my calculations are perfect. I need help with calculating the operating leverage for software and keyboard divisions, and need some help explaining the assumptions and calculations for each. The attached files gives a good ...continues
Growth in Profits - Degree of Operating Leverage?
If the sales of both software and deyboad divisions increase at the same rate, which will have the fastest growth in profits? I believe the key is derived by using DOL, or the degree of operating leverage. I am not sure how to apply this methodology to the sample data attached below.
Effect of Operating Leverage on Company's Risk Position
