Three Case Studies Using DiscoverSim™
Presenter: John Noguera, Co-Founder and CTO of SigmaXL
The Web Demo will cover the following three case studies.
1. Retail Profit Simulation:
This is an example of Monte Carlo simulation to determine probability of daily profit using a basic profit model for a small retail business. We will apply distribution fitting to historical data and specify input correlations to define the model in a way that closely matches our real world business. Sensitivity analysis will be performed to determine the key input factors affecting profit.
2. Magazine Production Optimization:
This is an example of simulation and optimization to determine optimal magazine production quantity for newsstand distribution to maximize net profit. A custom discrete distribution will be used to model customer demand.
3. Six Sigma DMAIC Project Portfolio Selection:
This is an example of discrete optimization used to select projects that maximize expected cost savings and minimize variability subject to a constraint of total resources.

How to Deal With Nonnormal Data in Process Improvement Projects
Presenter: John Noguera, Co-Founder and CTO of SigmaXL
This webinar will cover the real world issues around dealing with nonnormal data in process improvement projects. Topics will include:
Agenda:
- When do I need to worry about Nonnormal data (i.e., is the Central Limit Theorem working for me)?
- Guidelines on sample size for central limit theorem to work (for mild, moderate and severe skewness)
- Do I have Outliers or Inherently Nonnormal data?
- Do I need to stratify to deal with a bimodal distribution?
- How do I deal with Nonnormality due to measurement discrimination (“chunky” data)
- SigmaXL tools to detect Nonnormality
- Graphical Tools: Histogram, Boxplot, Normal Probability Plot, Control Chart
- Anderson Darling Normality Test
- SigmaXL tools to deal with Nonnormality
- Nonparametric Tests
- Transformations and Distribution Fitting

Introduction to Logistic Regression
Presenter: John Noguera, Co-Founder and CTO of SigmaXL
Have you ever wondered how researchers determine the odds of lung cancer versus risk factors such as years of smoking and number of cigarettes smoked per day?
Lung cancer (and other diseases) are discrete in nature. You either have cancer or you don't. Years of smoking and number of cigarettes are continuous predictors. So the tool researchers use is Binary Logistic Regression.
Binary Logistic Regression is also a powerful tool to help determine the root causes of manufacturing or transactional defects.
This webinar will introduce you to SigmaXL's Logistic Regression Tools.
Agenda:
- Introduction to Binary Logistic Regression (How it differs from Least Squares Regression)
- Data Format
- Interpretation of SigmaXL's Output
- P-Values
- Odds Ratios
- Pseudo R-Square
- Goodness of Fit Tests
- Residuals Analysis
- Event Probability Calculator
- Ordinal Logistic Regression
Demonstration: 40-50 minutes
