Description

The file Lamb_et_al_SAScode.txt contains SAS scripts and instructions for conducting nonlinear regression analyses of the Linum data set. The contents of the file can be pasted directly into the script editor in SAS. The file includes a script to import the Linum data set contained in the file Linumdata.txt into SAS.

The file Linumdata.txt contains 4 columns and 40 rows (39 data points, one row with column headings). The columns in the data set are as follows:

	ID: row number
	fert: fertilization treatment (g NPK added to each pot)
	AN Biomass: Aboveground Biomass (g) of plants exposed to competition from neighbors.
	NN Biomass: Aboveground Biomass (g) of plants separated from competition by neighbors.
