Of the three quantitative forecasting techniques (moving
average, weighted moving average, and exponential smoothing), which
do you think provides the most accurate forecast and why?
Forecasting methods studied in this class are quantitative
techniques including moving average, weighted moving average,
exponential smoothing, linear regression, and exponential smoothing
with trend component.
You are given a set of past demand data and asked to forecast
demand for the future. What would you FIRST do to decide which
demand forecasting method to use and why? Please choose one of the
forecasting methods listed above.
1. Evaluate the forecasting model using 3 month moving
average, and 3 month moving weighted average, and exponential. The
weights are .5 for the most recent demand, .25 for the other
months. Alpha = .3. Use the weighted moving average for January
Forecast.

Suppose that you are using the? four-period weighted moving
average forecasting method to forecast sales and you know that
sales will be decreasing every period for the foreseeable future.
What of the following would be the best set of weights to use?
(listed in order from the most recent period to four periods? ago,
respectively)?
A.0.00, 0.00,? 0.00, 1.00
B.?0.25, 0.25,? 0.25, 0.25
C.?1.00, 0.00,? 0.00, 0.00
D.0.10, 0.20,? 0.30, 0.40
E. ?0.40, 0.30,? 0.20, 0.10

What
are the ledgers, why do we use them?
And
then HOW do we use them, how does information get into them how do
balances get extracted. And then what should the balances for
various accounts be, i.e. assets, liabilities, expenses, revenues,
equity, dividends. Why SHOULD they have a particular balance as
either debit or credit.
