You've made a forecast using a simple exponential smoothing model based on past sales from 100 periods. By minimizing rMSE between your forecast and actual sales data, you can find the optimal value for alpha. Suppose there is a large shock to your actual sales and the shock happened in period 50; how would you anticipate this affecting the newly optimal value of alpha? Group of answer choices New optimal alpha is larger in value than old optimal alpha New optimal alpha is smaller in value than old optimal alpha
