**[ME] estat sd** -- Display variance components as standard deviations and
correlations

__Syntax__

**estat** **sd** [**,** __var__**iance** **verbose** **post** __coefl__**egend**]

__Menu for estat__

**Statistics > Postestimation**

__Description__

**estat sd** displays the random-effects and within-group error parameter
estimates as standard deviations and correlations.

__Options__

**variance** specifies that **estat sd** display the random-effects and
within-group error parameter estimates as variances and covariances.
If the **post** option is specified, the estimated variances and
covariances and their respective standard errors are posted to **e()**.
**variance** is allowed only after **menl**.

**verbose** specifies that the full estimation table be displayed. By
default, only the random-effects and within-group error parameters
are displayed. This option is implied when **post** is specified.

**post** causes **estat sd** to behave like a Stata estimation (e-class) command.
**estat sd** posts the vector of calculated standard deviation and
correlation parameters along with the corresponding
variance-covariance matrix to **e()**, so that you can treat the
estimated parameters just as you would results from any other
estimation command. For example, you could use **test** to perform
simultaneous tests of hypotheses on the parameters, or you could use
**lincom** to create linear combinations.

The following option is not shown in the dialog box:

**coeflegend** specifies that the legend of the coefficients and how to
specify them in an expression be displayed rather than displaying the
statistics for the coefficients. This option is not supported by
**mixed**.

__Examples__

Setup
**. webuse pig**
**. mixed weight week || id: week, covariance(unstructured)**

Display the estimated variance components as correlations and standard
deviations
**. estat sd**

Same as above, but display the full estimation table
**. estat sd, verbose**

__Stored results__

**estat sd** stores the following in **r()**:

Matrices
**r(b)** coefficient vector
**r(V)** variance-covariance matrix of the estimators

If **post()** is specified, **estat sd** also stores the following in **e()**:

Matrices
**e(b)** coefficient vector
**e(V)** variance-covariance matrix of the estimators
