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.

Answer:

85.5 reals

Step-by-step explanation:

Aqui, usando a função de análise, queremos saber a quantidade de dinheiro que deve ser investido para fornecer o número de visualizações.

A maneira como podemos resolver isso é através da substituição. Precisamos apenas substituir F (x) na equação e resolver x, o que nos dará a idéia da quantidade de dinheiro a ser investido.

matematicamente

F (x) = 40x + 80

3500 = 40x + 80

40x = 3500-80 40x = 3420 x = 3420/40

x = 85,5 reais
