Let me guess, you never dereferenced the -local-s for the -max- calculation? Note the difference here:
*************
local m_108 2.33
local m_109 3.4
local m_1010 1.2
//with dereferencing
di max(`m_108', `m_109', `m_1010')
//w/o dereferencing
di max(m_108, m_109, m_1010)

Betreff: Re: st: re: Programming stata using egen functions
Hi
Thanks for your response.
I am a beginner in stata programming but my aim is to create a “mean”
of the variable logwage to after run the bootstrap.
So when I use rowmax( ) I expect the program to calculate the maximum
of the value of the variables in parenthesis. For each `s’ I need the
maximum value between the `sp’ numbers.
For example: m_108 = 2.33
m_109 = 3.4
m_1010= 1.2
So I want the program to return de value 3.4. When I use the function
max the program returns me the value of m_1010 because it is
considering the max between the values 108, 109, 1010.
So after the program calculate the maximum value within it m_`s’`sp’ ,
I trying to use the rowtotal( ) to sum all of the maximum values and to
end up with just one variable.
Thanks
Anne
