Functions

check_input_preconditions(): Check preconditions for an input data frame for the prepare_data_frame and jb_rule_check functions.
dd_hyperbolic_model(): This function gets model parameter estimates for each group, including hyperparameters and estimates of the variance components (the observation error and subject random effect). It also gets F-test results for pairwise equality for the hyperparameter for each pair of groups, and overall equality of all hyperparameters.
estimate_hyperbolic_model_params(): Estimate the hyperparameters for each group, as well as the variance components of the model, using maximum likelihood estimation.
get_subj_est_ln_k(): Return ln(k) estimates for each subject.
hyperbolic_model_f_test(): Perform an F-test for equality of some combination(s) of hyperparameters.
jb_rule_check(): Apply Johnson-Bickel rule checks to each subject.
prepare_data_frame(): Prepare a data frame containing discounting for use on the other functions in this package.
simulate_dataset(): Simulate a dataset from the hierarchical linearized hyperbolic model.
