succeeding years from 2011 to 2015 we have used the Statistical StraightLinemethod ( Yc= a+bx ) in projecting the demand for the next 5 years. We used this method since the method yielding to the lowest standard deviation and most likely to give the best reliable forecast among the 4 methods...

2.1.2 The Least Squares Regression Line
The least squares method of obtaining a regression line has a mathematical base which involves all values and therefore considered superior. The least squares regression line of y on x axis is that line which the sum...

The happiest circumstance is that where a simple straightline/linear trend seems to provide an adequate summary of the main movement of the time series.

1. It uses all the observations
2. The straightline is obtained by an objective, statistical and procedure.
3. A measure of goodness of fit is available.
DISADVANTAGES
1. The method is somewhat more complicated than the methods discussed earlier.
2. Result of such an analysis are...

straightline can be numerically calculated by the following formula:
b = (Y2 – Y1) / (X2 – X1)
On the basis of this equation, we can now find the values of the dependent variable Y for varying values of X.

arithmetic sequence: 700, 700, 700, 700
4(2800)/10 = 1120 , 3(2800)/10 = 840 , 2(2800)/10 = 560 , 1(2800)/10 = 280
Arithmetic sequence: 1120, 840, 560, 280
The value of the computer drops $2800 in 4 years (from $3000 to $200). So in turn using the straightlinemethod this is $700 per year since 2800...
