I am trying to insert this code:
forvalues i=1/`nparam' {
qui sum est if dumyid == `i'
local avest = r(mean)
local between = r(Var)
qui sum `v' if dumyid == `i'
local m=r(N)
local within = r(mean)
local totalv = `within' + ( 1 + 1/`m' )*`between'
if `between'==0 {
global mi_combine3 F
}
if `between'<=0 {
local dof .
local ii=`i'*$mimps
local lb=lb in `ii'
local ub=ub in `ii'
local riv=0
}
else {
local dof = ( 1 + 1/`m' )*`between'
local riv = `dof'/`within'
local dof = (`m'-1)*(1 + 1/`riv')^2
if `dof'>1e+10 { local dof=1e+10 }
local invt = invttail(`dof', (1-`level'/100)/2)
local lb = `avest' - `invt' * sqrt(`totalv')
local ub = `avest' + `invt' * sqrt(`totalv')
}
post `memhold' (`i') (`avest')/*
*/ (`totalv') (`dof') (`lb') (`ub') (`riv')
}
postclose `memhold'
/* Merge back individual results */
qui use "`results'",clear
qui sort dumyid
qui merge dumyid using `abit'
keep parm est* se* lb* ub* avest totalv mi* obs* riv
order parm avest totalv mi* riv
qui compress
qui save `outfile', replace
end
into my program. This is the mi_rubin.do file.
I have three questions. 1) Is the variable `within' need to have the quotes
around it?
2) I am using a semicolon (;) as a designation of the end of command line.
Do I need to have a ; after each command withing inthe {} in the forvalues
statement. For example should it read: f
forvalues i=1/`nparam' {;
qui sum est if dumyid == `i';
local avest = r(mean);
local between = r(Var);
qui sum `v' if dumyid == `i';
local m=r(N);
local within = r(mean);
local totalv = `within' + ( 1 + 1/`m' )*`between';
if `between'==0 {;
global mi_combine3 F;
};
or just one ; after the close bracket(shown below)?
forvalues i=1/`nparam' {
qui sum est if dumyid == `i'
local avest = r(mean)
local between = r(Var)
qui sum `v' if dumyid == `i'
local m=r(N)
local within = r(mean)
local totalv = `within' + ( 1 + 1/`m' )*`between'
if `between'==0 {
global mi_combine3 F
}
3) in the forvalues statement, if I have i=1/6 I keep getting an invalid
forval error r(196). I assumed the `nparam' meant the number of
parameters.
If anyone is familiar with this rountine and can help me, I would
appreciate it. I am new to STATA. Thanks. Lieu
