machine capacity. Our goal was to buy additional machines whenever a station reached about 80% of capacity. Day 50 Once the initial first 50 days of data became available, we plotted the data against different forecasting methods: Moving average, weighted moving average, exponential smoothing, exponential smoothing with trend, and exponential smoothing with trend and season. Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%)

Y,S,Z,P C. K. Use regression to estimate K. Log S=logK + logY + logX – logP To find the antilog of K, use the exponential logK. 5. Use Excel. Fill in the numbers. Look under 5 year moving average. Click on exponential smoothing tab. Look at the smoothing factor. Look at MSE for each mean squared errors. Use the MSE to choose the one that will give you the best focus and that would be the one with the smallest MSE. 6. A.

1. Modern Electronics specializes in manufacturing modern electronic components. It also builds the equipment that produces the components. Modern Electronics is considering building a new facility but the estimated profits would be impacted by the type of market that develops. The probability for a strong market is 0.3; for a fair market is 0.5; and for a poor market is 0.2. You are responsible for advising the president of Modern Electronics on the type facility that should be built or to not

main idea is to find the average return and VaR when we buy at the time MACD shows a “golden cross” and sell at the time when there is a “death cross”. MACD: Before we do the test, let’s start to define the MACD as well as its components. MACD is one of the most popular indicators used in the technical analysis. And it is mainly comprised of MACD line, signal line, and the histogram. MACD line and the signal line are calculated by using the EMA (exponential moving average) function, while the histogram
