Title

buckley --    Buckley-James method for analysing censored data

Syntax

buckley depvar censorvar varlist [, options]

options                Description
-------------------------------------------------------------------------
Main
iterate(#)           specifies the maximum number of iterations
tolerance(#)         specifies the convergence criterion
dispnum(#)           specifies how frequently to display the iteration
-------------------------------------------------------------------------

Description

buckley uses the Buckley-James method (Buckley and James 1979) to
estimate the regression coefficients and generate the expected value of
the censored outcome.  depvar is the dependent variable whose value is
rightly censored when the censoring variable censorvar=1.  Otherwise it
is observed exactly when censorvar=0.  varlist is a list of explanatory
variable names. At least one explanatory variable must be specified.

Options

iterate(#) specifies the maximum number of iterations allowed in the
optimization.  It must be a positive integer. The default is
iterate(100).

tolerance(#) specifies the convergence criterion defined as the change of
the sum of squares of the difference of regression coefficients
between iterations.  It must be a positive number between 0 and 1.
The default is tolerance(1e-6).

dispnum(#) specifies how frequently to display the iteration; For
example, dispnum(50) displays every 50th iteration. # must be a
positive integer. The default is dispnum(100).

Examples

use aids, clear

gen censor = 1 - aids

gen age30 = age - 30

buckley time censor age30, i(20) t(1e-6) d(10)

tabstat time varbj, by(aids) stats(n mean sd min max) col(stats) f(%7.2f)
