Answer:

(a) MAE = 5.20

(b) MSE = 10

(c) MAPE = 38.60%

(d) Forecast for week 7 = 14

Step-by-step explanation:

Note: See the attached excel for the calculations of the Error, Error^2, and Error %.

(a) mean absolute error

MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20

(b) mean squared error

MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10

(c) mean absolute percentage error (Round your answer to two decimal places.)

MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%

(d) What is the forecast for week 7?

Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:

Forecast for week 7 = 14

How many labeled points are between points b and u ?
Olenka [21]

Answer:

It is difficult to give a specific answer without your scenario but maybe this may help you out a bit.

Let's say you have a line like the one attached:

I labelled certain points b and u so you can use it as a reference. Now all you need to do is count all the points that lie on the same line and are found between.

In this case it would be point d and point e because the rest of the points do not line on the same line. For this problem particular scenario, the answer would be 2.
