QUANTITATIVE ANALYSIS
The process of determining the value of a security by examining its numerical, measurable characteristics such as revenues, earnings, margins, and market share. A business or financial analysis technique that seeks to understand behavior by using complex mathematical and statistical modeling, measurement and research. By assigning a numerical value to variables, quantitative analysts try to replicate reality mathematically. In broad terms, quantitative analysis is simply a way of measuring things.


DECISION THEORY MODELS
Decision theory is an interdisciplinary area of study that concerns mathematicians, statisticians, economists, philosophers, managers, politicians, psychologists and anyone else interested in analyses of decisions and their consequences. it is concerned with identifying the best decision to take, assuming an ideal decision maker who is fully informed, able to compute with perfect accuracy, and fully rational. The practical application of this prescriptive approach (how people actually make decisions) is called decision analysis, and aimed at finding tools, methodologies and software to help people make better decisions. The most systematic and comprehensive software tools developed in this way are called decision support systems.


DECISION TREES
(or tree diagram) is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal. Another use of decision trees is as a descriptive means for calculating conditional probabilities.


FORECASTING
the process of estimation in unknown situations. Prediction is a similar, but more general term. Both can refer to estimation of time series, cross-sectional or longitudinalhydrology, the terms "forecast" and "forecasting" are sometimes reserved for estimates of values at certain specific future times, while the term "prediction" is used for more general estimates, such as the number of times floods will occur over a long period. Risk and uncertainty are central to forecasting and prediction. Forecasting is used in the practice of Customer Demand Planning in every day business forecasting for manufacturing companies. The discipline of demand planning, also sometimes referred to as supply chain forecasting, embraces both statistical forecasting and a consensus process.Forecasting is commonly used in discussion of time-series data.


LINEAR PROGRAMMING
In mathematics, linear programming (LP) is a technique for optimization of a linear objective function, subject to linear equality and linear inequality constraints. Linear programming determines the way to achieve the best outcome (such as maximum profit or lowest cost) in a given mathematical model and given some list of requirements represented as linear equations.

Linear programming can be applied to various fields of study. Most extensively it is used in business and economic situations, but can also be utilized for some engineering problems. Some industries that use linear programming models include transportation, energy, telecommunications, and manufacturing. It has proved useful in modeling diverse types of problems in planning, routing, scheduling, assignment, and design.

RDBMS

A relational database management system (RDBMS) is a program that lets you create, update, and administer a relational database. Most commercial RDBMS's use the Structured Query Language (SQL) to access the database, although SQL was invented after the development of the relational model and is not necessary for its use.
The leading RDBMS products are Oracle, IBM's DB2 and Microsoft's SQL Server. Despite repeated challenges by competing technologies, as well as the claim by some experts that no current RDBMS has fully implemented relational principles, the majority of new corporate databases are still being created and managed with an RDBMS.

Blue moon in tayabas


i Captured this the first time i went to tayabas.






Tayabas with the best panoramic view of Mt. Banahaw.


Tayabas is a special community. Of all the towns around Mount Banahaw, Tayabas has the best panoramic view of this vulcan de agua now regarded as the mystical mountain of the Philippines, which is host to at least half a million pilgrims during Holy Week.


One of the famous occassion that celebrate in Tayabas is Mayohan sa Tayabas, It's a 10 days celebration, from may 6-15. Its a season for the Tayabanses to converge at the mother navel of Quezon province.

Mayohan sa Tayabas is a program of the municipal government that aims to facilitate the process of conscious recollection among community members. Through a 10-day celebration, the Tayabanse is guided to honor the glory and bless the wounds and sacrifices of the past.



I will be posting more of tayabas soon..

Risk management/Risks in cigarette smoking

Risk Management aims to facilitate the exchange of information and expertise across countries and across disciplines. Its purpose is to generate ideas and promote good practice for those involved in the business of managing risk. All too often assessments of risk are crudely made and the consequences of getting things wrong can be serious, including lost opportunities, loss of business, loss of reputation and even life.

There are many risks of smoking and the purpose of this article is to outline the specific risks that are associated with smoking.

  1. Smoking kills over 400,000 people a year - making it more lethal than AIDS, automobile accidents, homicides, suicides, drug overdoses, and fires combined. Smoking may be even more dangerous now than 30 years ago, most likely because the lower tar and nicotine levels in most cigarette brands cause people to inhale more deeply.
  2. Second-hand or side-stream smoke are also at risk - Smoke that is exhaled not only contains the same dangerous contaminants as inhaled smoke, but the exhaled smoke particles are smaller, so that they can reach distant sites in the lungs of involuntary or passive smokers and do great harm.
  3. Smoking a cigarette raises the blood pressure by 5-10 mm Hg for about 30 minutes.
  4. Greatly increases your risk of heart disease.
  5. Addiction
  6. Smoking Related Cancers: Adult Acute LeukemiaAdult, Chronic LeukemiaCervical,CancerEsophagus Cancer, Laryngeal Cancer, Lung Cancer, Kidney Cancer, Oropharyngeal Cancer, Pancreas Cancer, Stomach Cancer, Urinary Bladder.

How to mitigate and probably control these risks:

  1. List all the reasons you want to stop - Every night before going to bed, repeat one of the reasons 10 times.
  2. Decide positively that you want to stop - Try to avoid negative thoughts about how difficult it might be.
  3. Develop strong personal reasons to stop in addition to your health and obligations to others.
  4. Begin to condition yourself physically - start a modest exercise program; drink more fluids; get plenty of rest; avoid fatigue.
  5. Have realistic expectations - stopping isn't easy, but it's not impossible either.
  6. Ask your partner or friend to stop with you.
