We use a form of small area estimation in which survey data is carefully modelled, and the parameter estimates applied to national, small area administrative data. As a result we can produce a detailed map for the survey target variable which is of great value in marketing.

Predictive analytics in manufacturing uses models extracted from historical order and production related records to support the optimization of manufacturing processes. For instance, forecasting the overall amount of incoming orders is crucial for a) properly scheduling and sizing raw material and part orders and b) configuring processes as e.g. final assembly or testing. Loosely based on a specific subproblem in one of our ongoing R&D projects, this howto showcases the process of building an order amount predictor in R.

Introduction

One of the more important aspects for applying Quality Improvement in Healthcare is the reporting of information on a timely and continuous basis.

Researchers overpromise and undeliver on patient accrual, the time frame in which they plan to obtain the proposed sample sizes for their research studies. It is not uncommon for a researcher to promise to get 100 patients within a year, but then struggle to get even a dozen patients after two years. Slow patient accrual leads to delays in completion of the study or sample size shortfalls or both.

Introduction

The workbook enables finance and business end users to use R routines without having to learn a new language. Specifically this workbook automatically fits best forecasting model for the input series and outputs forecasts for the horizon specified. The R package used in the application is "Forecast" by Rob Hyndman and REXCEL.

I have a paper under review at a journal where I (along with my co-author) provided theoretical verification for applying the Pythagorean Won-Loss formula to hockey. Originally devised for baseball, the Pythagorean Won-Loss formula estimates the percentage of games a team should have won at a particular point in a season. For decades, this formula had no mathematical justification from first principles. In 2006, the second author provided a statistical derivation by making some heuristic assumptions about the distributions of runs scored and allowed by baseball teams.
