MAPE: Mean absolute percentage error
In measures: Performance Measures for Statistical Learning

Defined as the abs(truth_i - response_i) / truth_i. Won't work if any truth value is equal to zero. In this case the output will be NA.

1	MAPE(truth, response)

`truth`	[numeric] vector of true values
`response`	[numeric] vector of predicted values

n = 20
set.seed(123)
truth = rnorm(n)
response = rnorm(n)
MAPE(truth, response)
