# Below, assume X is a shinystan object and two of the

# Add parameter gamma = inverse-logit(beta) to X
inv_logit <- function(x) 1/(exp(-x) + 1)
X <- generate_quantity(sso = X,
                       fun = inv_logit,
                       param1 = "beta",
                       new_name = "gamma")


# Add parameter delta = (alpha-beta)^2 to X
X <- generate_quantity(sso = X,
