statistics - Contingency table in Python -

-

given 2 lists of equal length, how can construct contingency table in pythonic way? know confusion_matrix skit-learn, there 'manual' , effective ways that?

you can use pandas library create table shown in wikipedia example, so, 

import pandas pd right_handed = [43, 44] left_handed = [9,4] df = pd.dataframe({'right': right_handed, 'left': left_handed}, index = ['males', 'females'])

this yields dataframe, so,

in [3]:  print (df)           left  right males       9     43 females     4     44

you can use sum totals,

print (df.left.sum())     print (df.right.sum())  13 87  in [7]:  print (df.ix['males'].sum()) print (df.ix['females'].sum())  52 48
