Abstract
beezdemand: Behavioral Economic Easy Demand, a novel 
package for performing behavioral economic analyses, is introduced and evaluated. beezdemand extends the 
statistical program to facilitate many of the analyses performed in studies of behavioral economic demand. The package supports commonly used options for modeling operant demand and performs data screening, fits models of demand, and calculates numerous measures relevant to applied behavioral economists. The free and open source beezdemand package is compared to commercially available software (i.e., GraphPad Prism™) using peer-reviewed and simulated data. The results of this study indicated that beezdemand provides results consistent with commonly used commercial software but provides a wider range of methods and functionality desirable to behavioral economic researchers. A brief overview of the package is presented, its functionality is demonstrated, and considerations for its use are discussed.

Notes
Although the term “method(s)” would also be appropriate here, we use the term “function(s)” to maintain consistent nomenclature within R Statistical Software.
A “data frame” in R nomenclature can be most easily thought of as a table, or as a single Microsoft Excel worksheet.
We note that 0.5 is the default value, but that beezdemand allows the user to specify the value of this added constant, and that future updates to the package will reflect the current state of best practices in the literature.
