I’ve developed tools to help researchers conduct behavioral economic analyses. Below are some of my key contributions.

shinybeez is an R Shiny app that allows analyses and visualizations of behavioral economic demand and discounting data. It relies on the beezdemand and beezdiscounting R packages. In addition to a comprehensive user guide, template files, and dark mode toggle, shinybeez includes the following features:

Demand

  • Descriptive, empirical (Intensity, BP0, BP1, Omax, Pmax), and regression (Q0, α, R2) results — all exportable
  • Systematic response-set screening with customizable bounce, trend, and reversal criteria
  • Exponential or exponentiated demand models; flexible k (1–4, individual, fitted, empirical range)
  • Fit to Group (pooled or mean) and Two Stage approaches
  • Results by grouping variable
  • APA-format plots with best-fit lines (pseudo-log axes; png, pdf, svg, and more)

Discounting

  • Nonlinear regression plus 27-Item MCQ and 5-trial minute-task scoring (delay and probability)
  • Scores the 27-Item MCQ identically to the Excel Automated Scorer
  • Hyperbolic (Mazur, 1987) or exponential models; none, log10, or natural-log transforms
  • Systematic response-set screening (Johnson & Bickel, 2008) and missing-data imputation, with exportable imputed-data tables
  • Full MCQ result tables: k values, consistency, LDR/LL proportions, summary statistics, correlations
  • APA-format plots: best-fit curves, SIR/SS choice proportions, k-value box plots
