The sample data is provided along with this in the file named “data.txt”

• The sample data is provided along with this in the file named “data.txt”
• Copy this data.txt to the foxpro parent folder and better it would be if you copy the dris.prg too to the FOXPRO folder.
• Run the dris.prg from the FOXPRO and enter as follows
Enter Input file name :data
Enter total no of samples :49
Enter no of parameters :12
Enter output filename :data or anything of your choice
In the data file the data are arranged in the following format
First is the yield and last column is the survey no.
Among the rows (records), there are 48 survey field records + the average mean of the whole population as the 49 th record. This
49 th record nutrient index value will be accounted for the whole area nutrient indices after analysis by the DRIS
Note: So the no of samples to be entered in the data entry includes the overallmean value also.

This was the output result of the dris progr am
These are the nutrient indices of the low yielding population
And the field no 48 remains to the DRIS nutrient indices for whole population for discussion further.
