	# Detecting correlation

	# Defines three functions using base R to illustrate techniques for identifying correlations
	# between continuous random variables, then tests against different types of data

	# Pearsons r, distance correlation, Maximal Information Coefficient (approximated)

	"""
	'When the frequency of an event varies as power of some attribute of that
	event the frequency is said to follow a power law.' (wikipedia)

	This is represented by the following equation, where c and alpha are
	constants:
	y = c . x ^ alpha
