Mlogit

[samaneh khaef]

Hi
I am stuch with simple Mlogit. I appreciate help
I am trying to see which regions are attracted by people with different ethnicity
so my regions as nominal var are my dependant.
then people's ethnicity is my predictor.
I simply did as below:
mlogit regions i.ethnicty
but I get the error no observation!

The sample of data is as below:

regions

A

B

C

D

E

for ethnicity

Ethnicity

Asian

African

European

how can I solve it?

this would be a lot easier to answer if you had followed the advice in the FAQ (please read it) and used -dataex- for your data example; my guess is that at least one of these two variable is string (rather than numeric) and needs to be encoded so it becomes numeric; see

help encode

and you probably want to set up your labels in advance and use the "label" option to the command

Thanks lot
Now when I use another variable for education which I have encoded, I got concave error.
the date:

The sample of data is as below:

Regions	code
A	1
B	2
C	3
D	4

for ethnicity

Ethnicity	code
Asian	1
African	2
american	3
European	4

Age as numerical variable

and Education

Education	code
Primary	1
elementary	2
tertiary	3

mlogit Regions i. Education i. Ethnicity age


where I have made a mistake?

and when I remove any of these variables randomly it works!
