“Famous	cell	phone	company	creates	credit	
products	for	possible	criminal	suspects.”

Big	Flop	5	
4/20/16	 J.S.Ramos	(@xuxoramos)	 9
Root	cause	
4/20/16	 J.S.Ramos	(@xuxoramos)	 10	
Survey	of	+200	data	
professonals.	Those	
coming	from	software	
development	have	a	
negative	correlation	with	
business.	When	this	red	
cloud	turns	into	a	deep	
blue	oval	with	positive	
slope,	Analytics	will	and	
must	be	born	in	IT.
How	do	we	turn	into	analysts?	
4/20/16	 J.S.Ramos	(@xuxoramos)	 11	
?? Hone	your	stats,	maths	and	optimization	skills.	Start	with	
matrix	algebra.	
?? Read	“Think	Stats”	by	Allen	Downey.	
?? Stop	automating	customs	and	start	improving	processes.	
?? Get	closer	to	your	business	and	learn	its	language.	
?? Learn	R.	It’s	ugly,	but	will	get	you	thinking	in	stats.	
?? Don’t	code	machine	learning	without	learning	stats!

“Forget	R	vs	Python.	The	best	language	for	data	
analysis,	[regardless	of	scale	or	sophistication],	is	
the	language	of	business!”

“Reality	does	not	reveal	itself	to	those	who	only	
contemplate	it,	but	to	those	who	immerse	in	it	to	
transform	it.”
