a one-dimensional string which is just the whole command line we want to Advanced Programming in Stata. Examples: Normal regression (easy) Logit and probit command varlist qualifiers, options. command 1, 2, orwords specifying the task varlist 0, 1,or more variables = exp A math or logical statement to set a value if exp A logical Advanced local macro manipulation Temporary objects Temporary variables: tempvar Temporary Matrices and vextors: tempname Temporary Files: tempfile Looping in Stata There are many advanced Stata programming concepts in this one single command! st_local() to access a local macro command varlist qualifiers, options. Understanding Stata Help Conventions. Type help command Stata files, macros, looping, etc. command 1, 2, orwords specifying the task varlist 0, 1,or more variables = exp A math or logical statement to set a value if exp A logical statement to limit cases, options Words and selectors to alter the command. Basic syntax. In general functions in Mata that interact with Stata objects use the st_ prefix, e.g. There are many advanced Stata programming concepts in this one single command! Programming your own maximum likelihood estimator. is treated just as any other do-ﬁle once it is executed; results are just the To run a Stata command we simply use the stata() function which takes a string scalar as argument, i.e. a one-dimensional string which is just the whole command line we want to execute in Stata. In writing our own likelihood function, we need the following information: – An understanding of some of Stata’s “ml” family of commands. Note: The help menus provide very useful information on MLE programming; help ml and/or help mlmethod – Log-likelihood function Advanced local macro manipulation Temporary objects Temporary variables: tempvar Temporary Matrices and vextors: tempname Temporary Files: tempfile Looping in Stata Looping using foreach Looping using forvalues Looping using while Branching in Stata with: if and elseWRITING STATA PROGRAMS Programming in Stata Do-files and ADO-files Likelihood functions. is treated just as any other do-ﬁle once it is executed; results are just the same as if you had started Stata and then typed run The only special thing about is that Stata looks for it and runs it automatically To run a Stata command we simply use the stata() function which takes a string scalar as argument, i.e.
