Usage

From the command window run the file by providing the path to the csv file and the axis limits

patient_name = python bland_altman.py --fname=path\to\csv\file.csv --minlimit=0 --maxlimit=100

Optionally the variables data labels can be specified with the arguments var1 and var2

python bland_altman.py --fname=path\to\csv\file.csv --minlimit=0 --maxlimit=100 --var1="Computed Plaque Burden" --var2="Measured Plaque Burden"

Output

The code returns the bland-altman plot and the concordance correlatoin plot and coefficient

Requirements
