Consider the following time series data: Month 1 2 3 4 5 6 7 Value 25 13 21 13 20 22 14 (a) Compute MSE using the most recent va

marishachu [46]

Answer:

a. MSE = 64.8

b. Forecast for month 8 is 14.

Step-by-step explanation:

$MSE = \frac{sum (error)^{2} }{n-1} \\$

where $error= value-forecast$

Using the most recent value as the forecast for the next period, we have forecasts for the months as;

(1,-) , (2,25) , (3,13) , (4,21) , (5,13) , (6,20) , (7,22)

$error$ = (-, -12, 8, -8, 7, 2, -8, -)

$error^{2}$ = (-, 144, 64, 64, 49, 4, 64, -)

$sum(error^{2} ) = 389$

$MSE = \frac{389}{7-1} = 64.833333$

Therefore, MSE = 64.8 (1 decimal place).

The Forecast for month 8 is 14 since we are using the most recent value as the forecast for the next period.

Proportionality or variation is state of relationship or correlation between two variables It has two types: </span>direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)</span>

12 × 4 = 48

12 can go into 50 4 times.
