Dear Micheil,
Many thanks for your time and reply. So, this is the latest form of the code. Is that ok now?
- we also add also attribute balance level for the weather to see less snowy weather.
;alts = bikeshare, bike, none
;rows=12
;alg=mfederov(stop = noimprov(3600 secs))
;bdraws = Halton(1000 ...

Re: constraints in Modified Federov Algorithm
Dear Micheil,
Thank you for your helpful comments.
This study will NOT have a pilot data collection stage.
So, in this case, do you mean we should use se=0 like [n, -0.00001, 0] or we could not have Bayesian D-efficient design at all and we should have D-efficient design using simply [-0.00001 ...

Re: constraints in Modified Federov Algorithm
Dear Michiel,
Thank you for your prompt and helpful reply.
1. To avoid perfect correlation, we removed some of the constraints but keep some constraints to satisfy our aim to keep10 min bike share free of charge (cost=0) as follows:
;reject:
bikeshare.cost_bikeshare= 0 and bikeShare.time ...

constraints in Modified Federov Algorithm
Dear Ngene Team,
Below is a labeled design code that my student is developed for his study.
1. He would like to have constraints for the time (10,15,20,25) and cost (0,1000,2000,3000) of bike-sharing. This means whenever the time is 10, the cost should be 0, time = 15 and cost = 1000, time = 20 ...

Syntax for Hybrid Choice Model
Dear Michiel,
Nowadays, the use of hybrid choice models (incorporating latent variables into the discrete choice models) have been getting popularity in different research area.
Is there any experimental design syntax as an example coded by Ngene for a hybrid choice model (discrete choice model ...
