Essay

Based on the following data,a forecaster used simple exponential smoothing and determined the following: S₀ = 19,S₁ = 18.6,S₂ = 19.08,S₃ = 19.064,S₄ = 19.851 and S₅ = 19.481. $$\begin{array} { c c } \text { Time } & \text { Demand } \\1 & 17 \\2 & 21 \\3 & 19 \\4 & 23 \\5 & 18\end{array}$$
-Calculate the Mean Squared Deviation (MSD).

Definitions:

Ethene

A colorless flammable gas with a faint sweet and musky odor, the simplest alkene with the chemical formula C2H4, used as a petrochemical precursor.

Constitutional Isomers

Compounds that have the same molecular formula but differ in the connectivity of their atoms, resulting in different chemical structures.

Geometric Isomers

Molecules with the same structural formula but differing in the spatial arrangements of atoms or groups of atoms, due to restricted rotation around a bond.

Alkenes

Hydrocarbons containing at least one carbon-carbon double bond, part of the unsaturated hydrocarbons.
