Thanks to Rick’s new book about SAS/IML, I realized that SAS/IML is far beyond PROC IML, and recently it added an advanced IML language called IMLPlus that enjoys many new features. I also start to play with SAS/IML Studio, an IDE exclusively for I…

Using SAS/IML for high performance VaR backtesting

Macros to estimate value at risk
Value-at-risk (VaR) measures the risk of loss on a specific portfolio of financial asset. Jon Danielsson introduced how to apply the nonparametric(historic simulation) and parametric methods to estimate univariate and multivariate VaRs [Ref. 1]. And t…
Macros for nonparametric VaRs
Value-at-risk measures the risk of loss on a specific portfolio of financial asset. The simplest ways are probably to imagine the daily returns as a normal distribution (or t-distribution) and therefore find the locations by probability. Jon Danielss…

Using PROC IML to deploy EWMA model for market risk
Exponentially weighted moving average (EWMA) model, which is a straight-forward moving average method in market risk, could memorize the finite market movements and address the relationship among multiple asset prices. Comparing with other multivariat…
