CB Predictor™  1.6—— User Manual使用手册
欢迎使用CB Predictor™


Welcome to CB Predictor, a powerful addition to the Crystal Ball suite of decision intelligence products!
欢迎使用CB Predictor，这是一个水晶球系统的附加的一个强大的决策产品！


Forecasting is an important part of many business decisions. Every organization needs to set goals, try to predict future events, and then act to fulfill the goals. As the timeliness of market actions becomes more important, the need for accurate planning and forecasting throughout an organization is essential to get ahead. The difference between good and bad forecasting can affect the success of an entire organization.
在商业决策中，预测是一个重要的部。每个企业都需要设立自己的目标，尝试去预测未来的发展趋势，然后采取行动去实现目标。随着及时的市场行动变的更为重要，这就需要我们在整个过程中能更准确的进行规划和预测。好的与坏的预测之间的差别是好的预测可以影响到一个组织的成功。


CB Predictor is an easy-to-use, graphically oriented forecasting add-in for Microsoft Excel spreadsheet users. If you have historical data in your spreadsheet, CB Predictor analyzes your data for trends and seasonal variations. It then predicts future values based on this information. You can answer questions such as, “What are the likely figures for next quarter’s sales?” or, “How much material do we need to have on hand?” With CB Predictor, you no longer need to pull these numbers out of thin air. Instead, you can rely on robust, statistically proven techniques to create these predictions accurately.
CB Predictor是一个易于使用的，自动加载在EXCEL中的预测向导图。如果在sheet中有历史数据，CB Predictor对数据的趋势和周期性变化进行分析，在历史数据的基础上预测未来的数值。您可以回答以下问题，如“下个季度的销售额可能是多少？”或者，“我们需要有库存在手头上？”使用 CB Predictor，你不需要再凭空的进行预测，你可以依靠完善的统计技术来进行准确的预测。


To get started, all you need is a spreadsheet containing historical data. From there, this manual guides you step by step, explaining forecasting terms and results.
若要开始使用CB Predictor，所有你需要一个包含历史数据的电子表格。本手册将引导您一步一步，解释条款和预测结果。

•Shampoo Sales tutorial
      香波销售案例
•How CB Predictor works
      CB Predictor如何工作
•Toledo Gas tutorial
      托莱多燃气公司案例

This chapter has two tutorials, a short one and a longer one, that provide an overview of CB Predictor’s features. The first tutorial, Shampoo Sales, is ready to run, using most of the defaults. The results forecast the next quarter’s worth of shampoo sales。
本章有两个案例，一个简单的一个复杂的，这两个案例是帮助我们更好的对CB Predictor的特性进行了解。在第一个香波案例中，有许多的误差，它是对下一个季度香波的销售值的预测。

The second tutorial, Toledo Gas, uses regression, previews the results, and customizes some features. The results predict the next year’s worth of residential gas usage for Toledo.
第二个Toledo Gas的案例，使用了回归分析，对结果进行评审，是对Toledo Gas明年的使用情况的预测.

Now spend some time learning how CB Predictor can help you forecast the future。

What is time-series forecasting? 什么是时间序列预测？
“Prediction is very difficult, especially if it’s about the future.”- Niels Bohr Nobel laureate in Physics
“预测是非常困难的，尤其是对未来的预测”——Niels Bohr 诺贝尔物理学奖获得者

How often are you asked to estimate future sales? Staffing requirements? Budget items? Do you need to predict numbers for the next year using historical numbers that are higher in the summer than the winter? Or numbers that rise and fall with the Dow Jones industrial average? if so, CB Predictor can help.
多久询问一次未来的销售量？员工配置需求？财政预算？你是否需要用比冬季更高的夏季的历史数据来预测明年的数据？或者是道琼斯工业平均指数的上涨和下跌？如果是的话，CB Predictor可以帮助你。

If you have historical time-series data, you can use CB Predictor to examine your historical data and predict future trends. You no longer have to assume that sales will be same as last quarter or that you will spend 10% more next year on expenses than this year. CB Predictor applies a battery of sophisticated statistical methods to your data series to find results that meet the strictest confidence requirements.
如果你有有时间顺序的历史数据，你可以使用CB Predictor工具来对历史数据进行评估并对未来的趋势进行预测。你不需要再去假设你的销售额会和上个季度的一样，也不需要再花费比去年多10%的开支。CB Predictor工具有一整套成熟的统计方法对你的历史数据进行分析，并根据严格的要求得到预测的结果。

CB Predictor uses two types of forecasting: time-series forecasting and multiple linear regression. Time-series forecasting breaks down your historical data into four components: level, trend, seasonality, and error. CB Predictor analyzes each of these components and then projects them into the future to predict likely results.
CB Predictor使用两种类型的预测方法：时间序列预测和多元线性回归方法。时间序列预测方法将你的历史数据从四个方面进行分析：水平、趋势、周期性和误差。CB Predictor对每个方面进行分析，并利用他们来预测未来最有可能的结果。

When you know that outside influences have an effect on the variable you want to forecast, you need regression. Regression takes historical data from the influencing variables and determines the mathematical relationship between these variables and your target variable. It then uses time-series forecasting methods to forecast the influencing variables and combines the results mathematically to forecast your target variable.
当你知道需要预测的变量收到外部因素的影响时，在预测是需要进行回归。回归是要对找到有影响因素的历史数据，并找到这些因素和预测变量之间的相互数学关系，然后运用时间时间序列预测的方法结合变量和目标变量之间的相互关系来进行预测。

After finding the best forecast for your data, CB Predictor pastes the forecasted values into your spreadsheet. You can also request detailed output that includes statistics, charts, reports, and PivotTables. CB Predictor can also create your forecasted values as Crystal Ball assumptions, ready for a “what-if” simulation.
当从数据中找到了最佳的预测值收，CB Predictor将预测结果粘贴到sheet表格中。你也可以要求详细的输出结果，包括统计数据、图表、报告和Pivto图。CB Predictor预测的数据可以作为水晶球的假设，为准备模拟做准备。

Shampoo Sales tutorial香波销售案例
The easiest way to understand what CB Predictor does is to apply it to a simple example. In this example, you are sales manager for Tropical Cosmetics Co. The company’s latest product, shampoo with tropical ingredients, has been in the marketplace for almost a year now. The vice president of marketing wants you to forecast the rest of the year’s sales of shampoo and decide whether to recommend investing in advertising or enhancements for this product.
CB Predictor最简单的理解方法就是进行案例的演示。在这个案例中，你是Tropical Cosmetics Co.公司的销售经理，这家企业最新的产品是有热带成分的洗发香波，该产品已经在市场是销售了近一年的时间。负责营销的副总希望你对今年剩下的时间的销售量进行预测，以便来决定是否在广告投入和产品改良中继续投资。

You have the weekly sales numbers for the last nine months.
你有过去9个月的每周的销售数据。

To begin the tutorial: 案例开始：
1.Start Crystal Ball and Excel.
1、打开水晶球（crystalball）和excel表格。
2.Open the Shampoo Sales spreadsheet from the Examples folder.
2、在案例文件夹中打开香波销售量的电子表格。
By default, the file is stored in this folder: C:\Program Files\Decisioneering\Crystal Ball 7\Examples\CB Predictor Examples.
该表格的默认地址是C:\Program Files\Decisioneering\Crystal Ball 7\Examples\CB Predictor Examples.


ps:我将Shampoo sales的表格上传给大家看看

Shampoo Sales.xls

lanj

In this spreadsheet, there is one column of Tropical shampoo sales data next to a column with dates from January 1, 2004 until September 23, 2004. You need to forecast sales through the end of the year, December 31, 2004.
在这张电子表格中，一列是热带香波的销售量的数据，边上一列是数据对应的时间，从2004年1月1日到2004年9月23日。你需要预测的是从现在到年底2004年12月31日的销售数据。

3.Select cell B4.
Selecting any one cell in your data range, headers, or date range initiates CB Predictor’s “Intelligent Input” to select all the filled, adjacent cells.
3、选择单元格B4
选择表格范围中任意一个单元格，以选择整个数据表格。

4.Select Run > CB Predictor.
4、选择Run>CB Predictor
The CB Predictor dialog, or wizard, opens to the Input Data tab as shown in Figure 1.2.
出现CB Predictor的对话框，按照图1.2显示的选取输入的数据范围。

Note: This command is only available if no simulation is running and the last run was reset. If necessary, wait for a simulation to stop or reset the last simulation.
注：此命令仅适合没有进行模拟运行的数据，如果有，需要将模拟停止或重新进行重置。
