Consider the following time series Quarter Year1 Year2 Year3
1 71 68 62
2 49 41 51
3 58 60 53
4 78 81 72
a. construct a time series plot. what type of pattern exist in the data
b. use the following dummy variables to develop an estimated regression equation to account for the seasonal effects in the data; Qtr1=1 if Quater 1,0 otherwise Qtr2=1 if Quater 2,0 otherwise Qtr3=1 if Quater 3,0 otherwise
c. compute the quarterly forecast for next year

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
