Question

The accompanying dataset shows the monthly number of new car sales in the last two years. Implement the Holt-Winters multiplicative seasonality model with trend. Find the best combination of α, β, and γ to minimize MSE.

α=0.2, β=1, γ=0.2; α=0.6, β=0.4, γ=0.6

First find the MSE for each set of values, α, β, and γ.

(Round to the nearest whole number as needed.)
