Extract Results from Delay-Discounting Model
Description
This function extracts model parameter estimates, fit statistics, and confidence intervals from a fitted delay-discounting model.
Usage
results_dd(fit_dd_object)
Arguments
fit_dd_object |
A fitted delay-discounting model object of class |
Value
A tibble containing the following columns:
-
id
: The participant or group ID (if applicable). -
term
: The model parameter (e.g.,k
). -
estimate
: The estimated value of the parameter. -
std.error
: The standard error of the parameter estimate. -
statistic
: The t-statistic for the parameter estimate. -
p.value
: The p-value for the parameter estimate. -
conf_low
: The lower bound of the 95% confidence interval. -
conf_high
: The upper bound of the 95% confidence interval. -
R2
: The coefficient of determination (R^2
).
Examples

id = rep(1:2, each = 6),
x = rep(c(1, 7, 30, 90, 180, 365), 2),
y = c(0.9, 0.5, 0.3, 0.2, 0.1, 0.05, 0.85, 0.55, 0.35, 0.15, 0.1, 0.05)
)
fit <- fit_dd(data, equation = "mazur", method = "two stage")
