Source material

The data set used in this example is stored in the Excel file CS4Data. This is the same data as used in Case Study 3 with minor changes in the variable field names. The fields are described in the associated word file CS4Doc. These fields include both data collected during the study and others derived during the earlier statistical analysis.

A number of variables (both original and derived) have already been defined as factors. The records without entries for weaning weight, either because the lamb died prior to weaning or because recording was missed, will be omitted from the analysis

Note that the first 4 rows of CS4Data contain the documentation for the data, so these need to be ignored when opening the file in GenStat.
