David - One way is to use -nl- See http://www.stata.com/support/faqs/lang/nl.html Al Feiveson -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of David Scheuer Sent: Tuesday, April 20, 2010 4:18 AM To: statalist@hsphsun2.harvard.edu Subject: st: Iterative solving of an equation I am rebuilding cost of capital models, which determine cost of capital implied as the internal rate of return from a valuation model. For instance, let me assume this is the first line in my dataset and I want to solve the following equation. Price_0 = 100 BookValue_0 = 50 EPS_1 = 3 BookValue_1 = 52 EPS_2 = 4.5 g = 0.04 x =? 100=50+(3-x*50)/(1+x)+(4-x*52)/((1+x)^2)+((4.5-x*54)*1.04)/((x-0.04)*(1+x)^2) For example, in Excel, I would let the "Solver" find the solution for x. How can I program STATA to find solutions like this for me? -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!
