lm regression query
Smells like homework to me. If so, we don't do homework on this list. -- Bert

Hello:
I have a 4-column dataset: Crime, Education, Urbanization, Age. I want to
construct a multiple linear regression to find the effect of Education,
Urbanization, and Age on Crime"
lm(Crime ~ Education + Urbanization + Age)
If I use + in above statement, does it mean it will build a model to find
the relationship between Crime and Education when Urbanization and Age are
held constant?
What would be the difference if I drop the term Urbanization + Age ?
lm(Crime ~ Education)
