Downside Risk Summary: Statistics and Stylized Facts
Creates a table of estimates of downside risk measures for comparison across multiple instruments or funds.
table.DownsideRisk( R, ci = 0.95, scale = NA, Rf = 0, MAR = 0.1/12, p = 0.95, digits = 4 )
R |
an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns |
ci |
confidence interval, defaults to 95% |
scale |
number of periods in a year (daily scale = 252, monthly scale = 12, quarterly scale = 4) |
Rf |
risk free rate, in same period as your returns |
MAR |
Minimum Acceptable Return, in the same periodicity as your returns |
p |
confidence level for calculation, default p=.99 |
digits |
number of digits to round results to |
