Hi, I do something similar by creating local matrices within my DO file, writing out the results of individual regressions to these matrices and finally displaying the matrix in stata. I can then easily copy and paste this into Excel (which is where I like to pretty my tables up - I know tabout is good in Stata but I've never found the term to learn it)... Here is some example code: *set a temporary name for the results table output by STATA tempname TmpTable matrix Results = J(4,9,.) // matrix to store results of mean commands below matrix colnames Results="Mean 1" "Mean 2" "Mean 3" "LB 1" "LB 2" "LB 3" "UB 1" "UB 2" "UB 3" matrix rownames Results= "Var 1" "Var 2" "Var 3" "Var 4" local RowNum = 0 // pointer to matrix row local ColNumMean // pointer to matrix column for mean local ColNumLB // pointer to matrix column for lower bound of confidence interval local ColNumUB // pointer to matrix column for upper bound of confidence interval foreach CountVar of varlist Var1 Var2 Var3 Var4 { //loop for variables *increment row local RowNum=1+`RowNum' foreach DelType of numlist 0 1 2 { //loop for mean types (DelType) *this is how I have my table set up... (see col names for matrix above) local ColNumMean=`DelType'+1 local ColNumLB=(`DelType'*2)+4 local ColNumUB=(`DelType'*2)+5 *this is where I do the actual regression quietly xtreg `CountVar' if TrialArm==0 & DeliveryType==`DelType', i(TrialCluster) re *r(table) is a very useful stata command that can be used to output all results into a matrix matrix `TmpTable'=r(table) /* matrix looks like this - for your regression command have a look at what r(table) returns! _cons b .49740385 se .0793922 z 6.2651476 pvalue 3.725e-10 ll .341798 ul .6530097 df . crit 1.959964 eform 0 I want elements [1,1], [5,1] and [6,1] */ matrix Results[`RowNum',`ColNumMean'] = `TmpTable'[1,1] matrix Results[`RowNum',`ColNumLB'] = `TmpTable'[5,1] matrix Results[`RowNum',`ColNumUB'] = `TmpTable'[6,1] } } *finally I display the matrix with headers to check it looks ok matrix list Results *to make it easier to copy and paste I display again without headers matrix list Results, nonames noheader Hope this helps!

I can't seem to work eststo and estout quite right. Here is the idea: Looping through an id# and 8 LHS varibles (RHS variables are the same) leaves me with 8 regressions per id from which I want a b, se, r2, N. Ideally, I want to save them as id#1 b1 (reg1) b1(reg2) b1(reg3)................ se (reg1) se(reg2).................. b2 (reg1)................................. se2 (reg1)................... r2(reg1) N(reg1) id#2 b1(reg1) se(reg1) etc.... In general would eststo and estout work here? I am having trouble creating an identifier for each regression using that, and then understanding how to stack it how I want to.
