Sample of Statistics Assignment Help Illustrations and Solutions: Illustration: 1 Convert the following annual trend equation into a monthly one: Yc = 24 + 1.8X Given X unit = 1 Year, and Y unit = annual production. Solution: By the formula of conversion of an annual trend to a monthly one we have : Yc = 𝒂 𝟏𝟐 + 𝒃𝑿 𝟏𝟐 ×𝟏𝟐 Substituting the respective values in the above we get, Yc = 𝟐𝟒 𝟏𝟐 + 𝟏.𝟖𝑿 𝟏𝟒𝟒 Or Yc = 2 + 0.0125X Where, X unit = 1 month and Y unit = monthly prodn.

Note. The above answer may be compared with the respective values of the annual equation given in the illustration 1.

4. Homework1 Copyright © 2014-2015 Homework1.com, All rights reserved Illustration: 3 Convert the following annual trend equation into a monthly order: Yc = 60 + 3.6X + 2.4𝑋2 Solution: By the formula of conversion of an annual equation of second degree parabola into a monthly one we have : Yc = 𝒂 𝟏𝟐 + 𝒃𝑿 𝟏𝟐 ×𝟏𝟐 + 𝒄𝑿 𝟐 𝟏𝟐 ×𝟏𝟐 ×𝟏𝟐 Substituting the respective values in the above we get, Yc = 𝟔𝟎 𝟏𝟐 + 𝟑.𝟔𝑿 𝟏𝟒𝟒 + 𝟐.𝟒𝑿 𝟐 𝟏𝟕𝟐𝟖 , = 5 + 0.025X + 0.0014 𝑋2 Where, X unit = 1 month, and Y unit = monthly value.

5. Homework1 Copyright © 2014-2015 Homework1.com, All rights reserved Illustration: 4 Convert the following annual trend equation into a quarterly one: Yc = 32 + 4.8X Solution: By the formula of conversion of an annual trend into a quarterly, one we have, Yc = 𝒂 𝟒 + 𝒃𝑿 𝟒 ×𝟏𝟐 Substituting the respective values in the above we get, Yc = 𝟑𝟐 𝟒 + 𝟒.𝟖𝑿 𝟒𝟖 = 8 + 0.1 X Where, X unit = 1 quarter, and Y unit = quarterly value of a variable. Illustration: 5 Given the trend equation, Yc = 240 – 1.8X, where X unit = 6 months, and Y unit = annual production. Convert the equation into a monthly trend.

6. Homework1 Copyright © 2014-2015 Homework1.com, All rights reserved Solution: Here, Y unit = annual production, and X unit is 6 months, So to convert the given equation into a monthly trend, we have to divide a by 12, but bX by 12 × 6. Thus the required equation will be : Yc = 𝒂 𝟏𝟐 - 𝒃𝑿 𝟏𝟐 ×𝟔 = 20 – 0.025X Where, X unit = 1 month, and Y unit = monthly production. Illustration: 6 Convert the following trend equation into an annual basis: Yc = 50 + 0.5X Where, the point of origin is Jan 2004, X unit = one month and Y unit = monthly sales (in ’000 $) Solution: Here, the origin of the equation is 15th ’04 (i.e. the midpoint of January) which needs to be shifted first to the 1st July ’04 (i.e. the midpoint of the yr. ’04) by 5.5 months forward. Hence, K = 5.5 By the formula of shifting a trend we have, Yc = a + b (X + K) = 50 + 0.5 (X + 5.5)

7. Homework1 Copyright © 2014-2015 Homework1.com, All rights reserved = 50 + 0.5X + 2.75 = 52.75 + 0.5X Now, by the formula of conversion of a monthly equation into an annual trend we have, Yc = a × 12 × bX (12 × 12) Substituting the respective values in the above we get, Yc = 52.75 × 12 + 0.5 × (144) = 633 + 72X Where, the point of origin = 2004, X unit = 1 year and Y unit = annual sales (in ’000 $). Note. The above problems required both shifting of the trend origin, and conversion of the trend equation. Since, the conversion was to be made from a lower time basis (i.e. monthly) to a higher time basis (i.e. annual) shifting, was made first and the conversion at the last.
