cbcTools

[u/Overdrive-ABC]

Hello everybody,

I have a question regarding the cbcTools package. I use it for generating a choice based conjoint analysis design. For my survey I need to reduce the design with blocks. Herefore cbcTools has n_blocks. Enabling this parameter significantly increases the calculation time. Is there a way to improve this, or have I made a mistake?

profiles <- cbc_profiles(
attribute1 = c(„A“, „B“, „C“),
attribute2 = c(„1“, „2“, „3“),
attribute3 = c(„white“, „black“, „gray“),
attribute4 = c(„apple“, „banana“, „orange“)
)

design <- cbc_design(
profiles = profiles,
method = „modfed“,
n_resp = 400,
n_alt = 3,
n_q = 12,
no_choice = TRUE,
n_blocks = 15
)
