The INBREED Procedure
The PROC INBREED statement invokes the INBREED procedure. Table 1 summarizes the options available in the PROC INBREED statement.
Table 1: PROC INBREED Statement Options
| Option |
Description |
| Specify Data Sets |
|
DATA= |
Names the SAS data set |
|
OUTCOV= |
Names an output data set to contain the inbreeding coefficients |
| Control Type of Coefficient |
|
COVAR |
Specifies that all coefficients output consist of covariance coefficients |
|
SELFDIAG |
Includes an individual’s self-mating kinship coefficient |
| Control Displayed Tables |
|
AVERAGE |
Produces a table of averages of coefficients |
|
IND |
Displays the individuals’ inbreeding coefficients |
|
MATRIX |
Displays the inbreeding coefficient matrix |
| Specify Default Covariance Value |
|
INIT= |
Specifies the covariance value |
| Suppress Output |
|
INDL |
Displays individuals’ coefficients for only the last generation |
|
MATRIXL |
Displays coefficients for only the last generation |
|
NOPRINT |
Suppresses the display of all output |
-
AVERAGE
A
produces a table of averages of coefficients for each pedigree of offspring. The AVERAGE option is used together with the GENDER statement to average the inbreeding/covariance coefficients within sex categories.
-
COVAR
C
specifies that all coefficients output consist of covariance coefficients rather than inbreeding coefficients.
-
DATA=
SAS-data-set
names the SAS data set to be used by PROC INBREED. If you omit the DATA= option, the most recently created SAS data set is used.
-
IND
I
-
displays the individuals’ inbreeding coefficients (diagonal of the inbreeding coefficients matrix) for each pedigree of offspring.
If you also specify the COVAR option, the individuals’ covariance coefficients (diagonal of the covariance coefficients matrix) are displayed.
-
INDL
displays individuals’ coefficients for only the last generation of a multiparous population.
-
INIT=
cov
specifies the covariance value cov if any of the parents are unknown; a value of 0 is assumed if you do not specify the INIT= option.
-
MATRIX
M
-
displays the inbreeding coefficient matrix for each pedigree of offspring.
If you also specify the COVAR option, the covariance matrices are displayed instead of inbreeding coefficients matrices.
-
MATRIXL
displays coefficients for only the last generation of a multiparous population.
-
NOPRINT
suppresses the display of all output. Note that this option temporarily disables the Output Delivery System (ODS). For more information on ODS, see Chapter 23, Using the Output Delivery System.
-
OUTCOV=
SAS-data-set
names an output data set to contain the inbreeding coefficients. When the COVAR option is also specified, covariance estimates are output to the OUTCOV= data set instead of inbreeding coefficients.
-
SELFDIAG
includes an individual’s self-mating kinship coefficient instead of the individual’s inbreeding coefficient on the diagonal of the matrix in the OUTCOV= data set when the COVAR option is not specified.
