Examination of pig growth rate

The script begins by defining a title for the output report: 'Examination of pig growth rate'. It then proceeds to create a dataset named 'Pigs' using a DATA step and the DATALINES clause. This dataset contains observations for the variables 'Group', 'Block', 'Treatment', and 'Weight'. Finally, the script executes the PROC LATTICE procedure on the 'Pigs' dataset, specifying the 'Weight' variable for analysis, which is typical for analyzing lattice experimental designs.

Data Analysis

Type : CREATION_INTERNE

The 'Pigs' dataset is created directly within the SAS script using a DATA step and the DATALINES clause, providing integrated raw data on pig growth.

DATA STEP Data

Explanation :
This DATA step creates a dataset named 'Pigs' and populates it with raw data provided via the DATALINES clause. The defined variables are 'Group', 'Block', 'Treatment', and 'Weight', representing experimental measurements for pigs.

PROC LATTICE

Explanation :
This procedure executes a lattice analysis on the 'Pigs' dataset. The 'var Weight;' statement specifies that the 'Weight' variable is the dependent variable to be analyzed within this experimental design.
