hyperparameters <- list(

Spent_Display_alphas = c(0.00001,9.9999),
Spent_Display_gammas = c(0.00001,1),
Spent_Display_shapes = c(0.00001,19.9999),
Spent_Display_scales = c(0.00001,1),

Spent_Meta_alphas = c(0.00001,9.9999),
Spent_Meta_gammas = c(0.00001,1),
Spent_Meta_shapes = c(0.00001,19.9999),
Spent_Meta_scales = c(0.00001,1),

Spent_Tiktok_alphas = c(0.00001,9.9999),
Spent_Tiktok_gammas = c(0.00001,1),
Spent_Tiktok_shapes = c(0.00001,19.9999),

Spent_Xandr_alphas = c(0.00001,9.9999),
Spent_Xandr_gammas = c(0.00001,1),
Spent_Xandr_shapes = c(0.00001,19.9999),
Spent_Xandr_scales = c(0.00001,1)

)
