Title

    ttable --            Mean Comparison for a lot of variables between two
         groups with formatted table output


Syntax

    ttable syntax varlist(min=1) [if] [in], by(varname),


    varlist is a list of numerical variables to be tested.  For each of those
    variables, we need to perform a standard t-test to compare her mean
    difference between two groups specified by by(varname)

    varname must be a dichotomous variable for the sample specified by [if]
    and [in]. varname maybe either numerical or string, provided that it only
    takes two different values for the sample.



A Simulated Examples


clear
set obs 1000

forval i = 1(1) 10 {
  gen x`i' = `i'+uniform()*`i'
  }
  gen num_d = uniform()>0.2+x1*.3+x2*.4-x3*.5
 
  gen xs = string(uniform())+"A"
  gen str_d = "A"
  replace str_d = "B" if x1<1.400
 
 ttable x1, by(num_d) 

 ttable x1 xs, by(num_d) 

 ttable x1-x10, by(num_d)

 ttable x1-x10, by(num_d)

 ttable x1-x10 xs, by(str_d)
  
 ttable x1-x10 in 1/800, by(str_d)
 
 ttable x1-x10 in 1/800 if x1<1.8, by(str_d)

 After Test
    Users can copy the output from Stata's result window, then paste to a MS
    word document. After that, highlight the pasted words and transform into
    a table.
