MIXED Procedure |
@MIXED performs mixed estimation on a linear regression. This combines the data evidence:
\({\bf{y}} = X\beta + {\bf{u}}\)
with the prior information
\({\bf{r}} = {\bf{R}}\beta + {\bf{v}}\)
This requires that you input as options the \(\bf{R}\) matrix, \(\bf{r}\) vector and information about the covariance matrix \(\bf{V}\) of \(\bf{v}\).
@MIXED( options ) depvar start end
# list of regressors (in regression format)
Parameters
|
depvar |
dependent variable |
|
start, end |
range for regression. By default, the maximum range permitted by all variables involved in the regression. |
Options
CAPR=\(\bf{R}\) matrix from above
LOWR=\(\bf{r}\) matrix from above
SCALAR=scalar multiplier when \(\bf{V}\) is scalar times the identity
V=\(\bf{V}\) matrix in general
