Udacity Machine Learning Nanodegree Bayes Rule Bayesian Analysis Walkthrough

quiz
<xi, di>
di = f(xi) + err
x, d, h(x) = x mod 9, h(x) = x/3, h(x) = 2,
1, 1, 1%9 = 1, 1/3, 2,
3, 0, 3%9 = 3,  1, 2,
6, 5, 6%9 = 6, 2, 2,
10, 2, 10%9= 1, 10/3, 2,
11, 1, 11%9= 2, 11/3, 2,
13, 4, 13%9 = 4, 13/3, 2,

sum of squared errors for each (excel calc)


h(x) = x mod 9
sum of squared errors = 12


h(x) = x/3
sum of squared errors = 19.44

h(x) = 2
sum of squared errors = 19

Use the smallest
Or better way: write a python script
