On Debian systems, you may install them by running:

sudo apt-get install python-numpy python-scipy

Install `stats-tools` by using `easy_install`:

sudo easy_install stats-tools

Or checkout from git repository:

git clone git://github.com/jweslley/stats-tools.git cd stats-tools sudo python setup.py install

All utilities take as input a file in table format to perform some calculation based on it. A tipical input file is shown below:

1 2 4 3 5 4 6 4 6 4 5 6 9 12 16

Considering this input file, let’s call it `example1.dat`, you can calculate some statistics like:

The `max` value on the first column:

max example1.dat

The `min` value on the second column:

min -c 2 example1.dat

You still can use negative column numbers to start counting from the right. Thus, the `sum` of the values on last column:

sum -c -1 example1.dat

If the input file’s columns are separated by another character instead of whitespace characters (space, tab, newline, return, formfeed), like CSV files, you can use the `-s` option to denote this. The next example outputs a statistical `summary` about the second column of the following file (`example2.dat`):

"A",10,12 "A",11,14 "B",5,8 "B",6,10 "A",10.5,13 "B",7,11

Calculating the summary:

summary -c 2 -s , example2.dat

Commonly, data files may contain a head, i.e., the first line describes the columns, something like the `example3.dat` file showed below:

Year,Make,Model,Description,Price 1997,Ford,E350,"ac abs moon",3000.00 1999,Chevy,"Venture ""Extended Edition""","",4900.00 1999,Chevy,"Venture ""Extended Edition, Very Large""","",5000.00 1996,Jeep,Grand Cherokee,"MUST SELL!air, moon roof, loaded",4799.00

The `-b` option remove the first line from calculations. In this case, the mean price of the cars is given by:

mean -b -s, -c-1 test/example3.dat

All `stats-tools` read data from standard input if no file is passed to them. The following command calculates the max value on the second column containing the word `bar` in the file `foo.dat`:

grep bar foo.dat | max -c 2
