@RISK Modeling Tips
In response to reader demand, the Palisade newsletter now has more modeling tips and examples. These tips and examples will cover real-life applications of @RISK and other Palisade tools, and many include spreadsheets you can download and try yourself. Last month we featured @RISK models calculating Value-at-Risk and Discounted Cash Flow. This month, learn about cost estimation, sports simulation, and new product profitability.

User Conference Series
Concludes in Latin America
Palisade is pleased to announce the success of its Latin America User Conference. Conducted entirely in Spanish and held at the Intercontinental Real in San Jose, Costa Rica on 26-27 November, 2007, the event attracted over 70 delegates. Participants included practitioners, academics, and consultants from across Latin America.

“We were very happy to meet professionals from banking, academia, oil and gas, and other industries,” noted Palisade Latin American Sales Director Denise Castellot. “The insights gained by both the delegates and staff made this a very valuable forum for quantitative risk and decision analysis.”

The San Jose conference was the fourth in a global series of User Conferences from Palisade in 2007 that commenced with an event in London in April, and included stops in Miami in October and Sydney, Australia in September. Attendance at the series in 2007 was more than double that of 2006, and events are being planned for 2008. Join us next year for what has become the industry risk and decision analysis forum!

Case Study

@RISK Used for Risk-informed Inspection at a Nuclear Power Plant
by Dr. Ching Ning Guey, Florida Power & Light,
presented at the 2007 Palisade User Conference

A risk-informed approach to inspect piping segments has been used in nuclear power plants since mid 1990s. In one NRC accepted methodology, @RISK is used to determine the relative importance of piping segments. Such an approach has been used successfully in maintaining the same level of safety, while reducing the burden of performing inspections. @RISK has been used in accounting for the uncertainties in two key aspects of the risk-informed inspection process, i.e., the likelihood of piping failures and the consequence of such failures.

Making $ense of Baseball –
An Econometric Approach

by Clay Graham, Analytical Advantages, LLC
Ever since the ancient Greeks first flipped a Drachma, gaming and probabilities have gone hand in hand. Baseball is unique in its finite nature of options when a batter faces a pitcher. There is no sports endeavor on earth that quantifies performance more than baseball. However, utilizing such information for gaming purposes is usually relegated to the “tipster” or “insiders”. The presentation covers:

  • Analyzing the cause and effect of run production
  • Building a detailed stochastic forecasting model of a baseball game
  • Integrating “lines and odds” into the economics of Expected Values of Return on Investment
  • Creating a wagering decision algorithm
  • Incorporating a control system

Building probabilities of winning and run production are brought together in a pragmatic manner (making smart bets) by utilizing the family of Palisade products, i.e, @RISK, StatTools, and BestFit.

Product Spotlight

Cost Estimation
When submitting a budget proposal for a project, two key questions that you are likely to be interested in are:

a) What is the probability that the project will actually be delivered within this budget?

b) How much contingency (i.e. extra budget) should be included in order for this new revised budget level to be achieved with a certain degree of confidence?

This model shows how one might answer these questions through @RISK Monte Carlo simulation: It is assumed that each item's actual cost will be within a min-max range, and that Pert distributions are applicable to describe the possible costs of each item in practice. The distributions are assumed to be skewed in this case, and the parameters chosen to reflect that costs are assumed to more likely overshoot than undershoot the base case. Results are given using @RISK statistics functions as well as through standard graphs and reports.

NCAA Tournament
This example lets you play out the NCAA tournament as many times as you want using @RISK Monte Carlo simulation. We factor in the abilities (through the SAGARIN ratings published in USA Today) of each team. Extensive data analysis has indicated that teams play on average to SAGARIN ratings and perform according to a standard deviation of 7 points about that level.

New Product Profitability
When a company develops a new product, the profitability of the product is highly uncertain. @RISK Monte Carlo simulation is an excellent tool to estimate the average profitability and riskiness of new products. The following example illustrates how simulation can be used to evaluate a new product. Imagine Pigco is thinking of marketing a new drug used to make hippos healthier. The model sets up the variables involved in marketing the new product, such as market size, use of the drug, whether competitors enter the market, etc.

Distribution of the Month

Beta Family of Distributions

RiskBeta
The Beta distribution is often used as a starting point to derive other distributions (such as the BetaGeneral, PERT and BetaSubjective). It is intimately related to the Binomial distribution, representing the distribution for the uncertainty of the probability of a Binomial process based on a certain number of observations of that process.

RiskBeta(alpha1,alpha2) specifies a beta distribution using the shape parameters alpha1 and alpha2. These two arguments generate a Beta distribution with a minimum value of 0 and a maximum value of 1.

For example, RiskBeta(1,2) specifies a beta distribution using the shape parameters 1 and 2. RiskBeta(C12,C13) specifies a beta distribution using the shape parameter alpha1 taken from cell C12 and a shape parameter alpha2 taken from cell C13.

RiskBetaGeneral
The BetaGeneral is directly derived from the Beta distribution by scaling the [0,1] range of the Beta distribution with the use of a minimum and maximum value to define the range. The PERT distribution can be derived as a special case of the BetaGeneral distribution.

RiskBetaGeneral(alpha1,alpha2,minimum,maximum) specifies a beta distribution with the defined minimum and maximum using the shape parameters alpha1 and alpha2.

For example, RiskBetaGeneral(1,2,0,100) specifies a beta distribution using the shape parameters 1 and 2 and a minimum value of 0 and a maximum value of 100.

RiskBetaGeneralAlt
RiskBetaGeneralAlt(arg1type, arg1value, arg2type,arg2value, arg3type,arg3value, arg4type,arg4value) specifies a beta distribution with four arguments of the type arg1type to arg4type. These arguments can be either a percentile between 0 and 1 or alpha1, alpha2, min or max. Both alpha1 and alpha2 must be greater than zero and max > min.

For example, RiskBetaGeneralAlt("min",0,10%,1,50%,20,
"max",50)
specifies a beta distribution with a minimum value of 0 and a maximum value of 50, a 10th percentile of 1 and a 50th percentile of 20.

RiskBetaSubj
The BetaSubjective distribution is rather like a BetaGeneral distribution in the sense that the range of the underlying Beta distribution has been scaled. However, its parameterization allows it to be used in cases where one wishes not only to use a minimum-most likely-maximum parameter set (as for the PERT distribution) but also to use the mean of the distribution as one of its parameters.

RiskBetaSubj(minimum, most likely, mean, maximum) specifies a beta distribution with a minimum and maximum value as specified. The shape parameters are calculated from the defined most likely value and mean.

For example, RiskBetaSubj(0,1,2,10) specifies a beta distribution with a minimum of 0, a maximum of 10, a most likely value of 1 and a mean of 2.
