Dear all,

I am a newbie in a simulation study. Here I created one simulated data using foreach command (n=500 t=5). I would also like to create 500 data and save them using this code. Would you help me to do so?

Thank you,


Code:
clear
drop _all


global obs        = 500        
global waves     = 5            
global corrXY    = .5    
global corrXZ     = 0        
global corrYZ     = 0     


foreach endox of numlist .1  {        
foreach endoy of numlist .2  {                                
foreach autox of numlist .2 {                        
foreach autoy of numlist .3 {                                        
foreach unob of numlist .5 {    

global autox    = `autox'    
global endox    = `endox'    
global endoy    = `endoy'    
global autoy    = `autoy'    
global betax    = 1            
global betaxlag    = 1            
global betay    = 1            
global betaylag    = 1            
global unob     = `unob'    


mat C =(1, $corrXY,$corrXZ \ $corrXY,1,$corrYZ \ $corrXZ,$corrYZ,1)
corr2data X Y Z, n($obs) corr(C)


gen id = _n 
expand = $waves 
bysort id: generate wave = _n  
replace wave = wave-1  

foreach var of varlist X Y Z {        
    replace `var' = . if wave >0    
}

xtset id wave
reshape wide X Y Z , i(id) j(wave) 

        
gen x0 = X0 + rnormal()            // xt1 + error rterm
gen y0 = Y0 + rnormal()            // yt1 + error term
gen z0 = Z0 + rnormal(0, 1.73)    // between var 3


foreach num of numlist 1/$waves{    // starts from wave 1        
gen x`num' = 3+ $autox* x`=`num'-1' + rnormal(0,1)     + ///
$endox* y`=`num'-1' + ($unob*z0) 
gen y`num' = 4+ $autoy* y`=`num'-1' + rnormal(0,1)     + ///
$endoy* x`=`num'-1' + ($unob*z0) 

}
}
}
}
}
}}
