AB Testing Simulation¶
Now that we’ve finished the AB testing calculation GIVEN data. How do we get the data?

The goal of this exercise is to create data like the one you see in your previous lesson. Here are some parameters:
There are 14 days and 1000 users
Assume user ids range from 0 to 999, hint: list(range(5))
Each user has a 50% chance of visiting each day. If they don’t visit, no views are created.
A user should be assigned to the same treatment/control group across the days!
Only 5% of the users should be assigned to treatment
A user’s distribution for views follows a $Geometric(p=0.1)$. Hint: numpy.random.geometric
A user’s distribution for clicks given their views follows a $Binomial(n=views, p_*)$, where $p_a$ and $p_b$, the probability of a click given a view for group A and B should be parametrized, i.e. coded so we can change it later. Hint: numpy.random.binomial
Compile all the data into 2 matrices, each are 1000 by 14, called clicks and views. Hint: numpy.vstack() or numpy.hstack()
Create an variable assign that contains the treatment/control status for each user.
What data type can this be? Later we will need to pull up user X’s treatment status quickly!
# assign can be a list or dictionary
assign = np.random.choice([‘Treat’, ‘Control’], size=n, p=[0.05, 0.95])
assign[:10]
array([‘Control’, ‘Control’, ‘Control’, ‘Control’, ‘Control’, ‘Treat’,
‘Control’, ‘Control’, ‘Control’, ‘Control’], dtype=’
return 0, 0
views = np.random.geometric(view_p)
clicks = np.random.binomial(views, ctr_prob)
return views, clicks
sim_click_views(0.05)
Finish the whole task! Try writing a loop within another loop, e.g.
for i in range(3):
for j in range(4):
print(i + j)
views = np.zeros((n, days))
clicks = views.copy()
for day in range(days):
for uid in range(n):
ctr = 0.05 if assign[uid] == ‘control’ else 0.1
view, click = sim_click_views(ctr)
views[uid, day] = view
clicks[uid, day] = click
Write the data to a file then try to download it!
Hint: numpy.savetxt
np.savetxt(“sim_ab_views.csv”, views, delimiter=’,’)
np.savetxt(“sim_ab_clicks.csv”, clicks, delimiter=’,’)
