Why does the following line of code result in an error as the following? The same syntax runs smooth when I use mfederov algorithm.

Error: The 'model' property contains an alternative with too many or too few '=' characters. 'u(alt1) = b1.dummy[0.00001] * guvenlikekipmani[0,1] + b2.dummy[0.00001 ...

Hello,

May I ask you to elaborate on the causes of the following error:
Warning: Defaulting to prior values of zero for the following priors: 'b1, b2, b3, b4, b5, b6, b7, b8, b9, '
Warning: One or more attributes will not have level balance with the number of rows specified: alt1.trafikyogunlugu ...

Hello,

When I add the line of;alg = mfederov to the following code, I cannot get a reasonable MNL D-Error value. Consequently, I get the following error: "The number of rows specified in the ';rows' property is greater than the size of the full factorial, which has 0 rows"; however, I get a ...

Hello,

May I kindly ask you to elaborate on why I cannot get any design out of this syntax?

Design
;alts = alt1*, alt2*
;rows = 100
;block = 20
;orth = seq
;model:
U(Alt1) = b1 * GuvenlikEkipmani[0,1] +
b2 * HavaDurumu[0,1] +
b3 * TrafikYogunlugu[0,1,2] +
b4 * Sigorta[0,1,2] +
b5 ...

Hello,

Thank you! I tried using the mfederov algorithm with continuous attributes, and it indeed ran faster.
Additionally, I noticed that edge cases did not occur as frequently. Am I missing anything?


Thank you once again,

Hello,

Thank you! I tried using the Mfederov algorithm with continuous attributes, and it indeed ran faster. Additionally, I noticed that only edge cases did not occur as frequently. Am I missing anything?

Also, may I ask if we could provide the software with a design and get its D-Efficiency ...

Thank you for your assistance so far.


I have the following design:

Design
;alts = alt1*, alt2*
;rows = 80
;eff = (mnl, d)
;block = 20
;alg = mfederov
;model:
U(Alt1) = b1.dummy[0.00001] * ToolSupply[0,1] +
b2.dummy[0.00001] * Weather[0,1] +
b3.dummy[0.00001|0.00001] * Traffic[0,1,2] +
b4 ...

Thank you for your response. I realize I had multiple questions in my previous post, which might have led to some being overlooked. May I kindly re-ask the unanswered ones?

Additionally, could you please explain the issue with the "Weather" attribute? Why should it be kept constant across ...

Hello,

I would like to ask if there is a way to obtain the final design in a modifiable format, such as Word, instead of PDF. This is important as I need to add related questions and explanations.

Additionally, I have an attribute with four categories: 0, 1, 2, and 3. The final output includes ...

Hello,

According to your suggestion, I fixed the levels for compensation per package, per km, and proportion of bike lanes on the route as follows:

" Design
;alts = alt1*, alt2*
;rows = 180
;eff = (mnl, d)
;block = 30
;model:
Design
;alts = alt1*, alt2*
;rows = 180
;eff = (mnl, d)
;block = 30 ...
