another test of code

cool feature

 
mata:

real colvector testMata(real colvector y,
                                    real matrix X)
  {[INDENT=2]
real colvector b

b = qrsolve(quadcross(X, 1, X, 1),quadcross(X, 1, y, 0)

return(b)
 [/INDENT]  }

Here is some code.

use melanoma, clear
keep if stage==1 /* restrict to localised */

stset surv_mm, fail(status==1 2) id(id) scale(12)

strs using popmort, br(0(0.5)10) mergeby(_year sex _age) ///
    by(sex agegrp) notables save(replace)

use grouped if sex==1 & agegrp==3, clear    
    
twoway (line cp end, lw(medthick)) ///
(line cp_e2 end, lw(medthick)), ///
yti("Survival") ///
ylabel(0(0.2)1, format(%3.1f)) ///
xti("Years from diagnosis") xla(0(1)10) ///
legend(order(1 "Observed" 2 "Expected") ring(0) pos(7) col(1))

graph export "graph.png", replace

Can we add an image?
