Forecasting in general is the process of predicting future occurrences. Business wise, forecasting is essential for all decisions related to budgeting, production, inventory, equipment, facilities, and workforces. Forecasting is categorized into quantitative and qualitative measures.
Quantitative is generally considered to be more accurate when a proper amount of historical data is available and the occurrences under investigation are stable. Qualitative is preferred when no historical data are available (eg, for new products) or when the occurrences under investigation are rapidly changing, making the past unable to explain the future, or in the case of unique exceptional events, such as sales promotions (Caniato, Kalchschmidt, & Ronchi, 2011, p. 413).
The focus in this research is on the quantitative methods, which mainly consist of time-series and associative forecasting methods.
A time series is a sequence of observations on a specific object over regular times (eg, days, months, and years), and sometimes over irregular ones. A good example of time series is the inflation rates...

Research can be quantitative and qualitative. Quantitative research is objective and involves measuring the phenomena under investigation. Qualitative research is subjective, explores experiences and feelings, and involves the recording of phenomena that cannot easily be quantified (Toates, 2010, pp. 5-6). Both are empirical since they involve data collection (OU, n.d.).
This paper analyzes the main economic indicators related specifically to one of the largest pharmaceutical company Pfizer, Inc such as overall performance, revenue, net income, research and development, cost and expenses. There are certain economic indicators that do not apply to individual companies, but influence their economical forecasts. Such factors as inflation and unemployment rate pertain to an industry or region and such factors as political instability or any force major conditions will affect the market analyses even they are not an economic indicators. There are many more factors that affect economic predictions and their detailed analyses are presented in http://www.economic-indicators.com, web site for tracking US economy.
Predictive Modeling: Utilization of the patterns discovered in the discovery step to forecast possible future conducts or behavior.
Use forecasting tools to prepare accurate forecasts for CMO and measure forecast accuracy every three months.
He uses trend exploration to determine his forecast. Since he is the sales person of his business he does his own forecasting. Trend exploration involves extending a pattern observed in past data into the future. He simply looks at the past sales of a few months or a year to try to come up with a projection for the next few months or year. This is a simple way of forecasting because trend exploration assumes that sales will remain the same, however, this may not always be the case.
The purpose of this paper is to explain the advances being made in technology and algorithms in helping advance the accuracy of forecasting. It will contrast the forecasting methods of several decades ago with forecasting methods in use today. In discussing how errors can accumulate over time and providing simple mathematical formulas as examples, this paper intends to show how the repetition of minor errors can affect the accuracy of weather predictions.
Yankee Fork and Hoe Company have an informal method of forecasting. First, marketing determines the forecast for the next upcoming month by meeting with managers from the sales regions. In these meeting they go over the previous demand, economic changes, and shortages they experienced. Through these meetings the marketing manager develops a forecast for the upcoming year, and then passes it onto production.

A discrete time stochastic process which is described as a sequence of random variables known as time series (Markov chain). The values of variables change at the fixed points of the time.
Each of them have the same goal, but use a different path to find contrasting info in various ways. Doing qualitative research gets you reasonings and explanations of certain issues or improvements a company can do. People who are surveyed are telling their own opinions and ideas in their own words. Companies take this into consideration and use this info collected for future reference. Qualitative data is collected by doing interviews, focus groups, and observations. This data is usually recorded in person, to get a true and more accurate answer. For example, if the business has a drop in sales, they gather people to tell them why people are not buying the products. Quantitative data, however is collected by polls, questionnaires, and surveys. A majority of these methods are not done in person, but are done using online surveys. These surveyors will get numbers, like how many people liked a certain product or the average age of customers. For simple and efficient ways of getting information in numbers, using technology is the fastest and easiest way to do this. All the company needs, is to send out these online polls or surveys to a large group of people. Unlike qualitative data, quantitative data can give you a more general idea of data and a bigger amount of it as well. Qualitative data takes time to find out and can only use a small sample
This Paper examines and compares various forecasting techniques used for qualitative and quantitative business forecasting and their use in Firstlogic Inc., to forecast the demand under conditions of uncertainty. Time series and Delphi forecasting methods are considered for this research to evaluate their ability to make effective decisions regarding the future.
Quantitative research may be seen as the less contentious of the two because it is more closely aligned with what is viewed as the classical scientific paradigm. Quantitative research involves gathering data that is absolute, for example numerical data so that it can be examined as unbiased as possible. The main idea behind quantitative research is that it is able to separate things easily so that they can be counted. The researcher generally has a clear idea of what is being measured before they start measuring it, and their study is set up with controls. Qualitative research on the other hand is a more subjective form of research, in which the research allows themselves to introduce their own bias to help form a more complete picture. Qualitative research may be necessary in situations where it is unclear of what is exactly being looked for in a study, while quantitative research generally knows exactly what it is looking for. Questionnaires and surveys are quantitative socio-legal research, because it is the collection of numerical data, or data that can be easily being turned into a numerical form. In terms of analysing quantitative data, Excel is the b...
