问题
I am trying to replicate some results from a study. therefore often i need to compare my regression results with results from the study that i'm trying to replicate. I have been manually combining my esttab results with the study results in excel. this however is tedious since i'm working with lot of variables. I was wondering whether there is a way to store the study results and then calling them to go next to my regression results. I tried storing them as scalars and calling them using estout however this puts the stored scalars below the regression results. i would prefer to have them side by side as another column.
Example:
Reference study results are
var b
x 2.1
z 4.2
I entered these into Stata
estadd scalar x=2.1
estadd scalar z=4.2
My regression is
eststore: reg y x z
estout, stats(x,z)
but when i do this i get a table like this
var b
my reg x 5.3
my reg z 2.3
scalar x 2.1
scalar z 4.2
But I would want the results like this
var b scalar b
my reg x 5.3 2.1
my reg z 2.3 4.2

The following might help. Find comments inline.

*----- example data -----
sysuse auto
keep price weight mpg
*----- what you want -----
//regress and store
reg price weight mpg
eststo m1
// create matrix of "scalars"
matrix w = (2.1 , 2.4 , 3.2)
// rename matrix columns to coincide with those of regression
mat colnames w = weight mpg _cons
// add
estadd matrix w
// print
estout m1, cells("b w")
