UpsideFrequency: upside frequency of the return distribution

Description

To calculate Upside Frequency, we take the subset of returns that are more than the target (or Minimum Acceptable Returns (MAR)) returns and divide the length of this subset by the total number of returns.

Usage

UpsideFrequency(R, MAR = 0, ...)

Arguments

R

an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns

MAR

Minimum Acceptable Return, in the same periodicity as your returns

...

any other passthru parameters

Details

$$UpsideFrequency(R , MAR) = \sum^{n}_{t=1}\frac{max[(R_{t} - MAR), 0]}{R_{t}*n}$$

where $n$ is the number of observations of the entire series

Examples

data(portfolio_bacon)
MAR = 0.005
print(UpsideFrequency(portfolio_bacon[,1], MAR)) #expected 0.542

data(managers)
print(UpsideFrequency(managers['1996']))
print(UpsideFrequency(managers['1996',1])) #expected 0.75
