The goal of the delaydiscount package is to provide methods for analyzing delay discounting data using the linearized hyperbolic model.
You can install the development version of delaydiscount from Github.
# install.packages("devtools")
devtools::install_git("https://github.com/davideh-vt/delaydiscount")To fit a model on a dataset of delay discounting data, first run
prepare_data_frame on the dataset, then run
dd_hyperbolic_model on the output.
library(delaydiscount)
## basic example of fitting a model
prep_remedi <- prepare_data_frame(remedi)
fit <- dd_hyperbolic_model(prep_remedi)
