Please let me know what you think. Writing test cases for performance testing requires a different mindset to writing functional test cases. Fortunately it is not a difficult mental leap. This article should give you enough information to get you up and running.
What about robustness you ask? The Moving Average System produces more uniform robust? Below is also a histogram of all individual returns per market per parameter combination, i. There is clearly more blue presence on the left side of the chart and more red one on the right side… A potential explanation Using some inductive logic warning: Below is an example of what I found: Crossovers for Cocoa The chart above only shows Moving Averages and Moving Medians the prices have been removed to make the picture clearer.
Average and Median seem to closely follow each other both on slow and fast sides. Indeed the bulk of the trades take place at roughly the same time i. However, if we zoom in over that red-circled congested area: Zoomed-in portion of Cocoa chart We can see that the Median Crossover system generates more signals than the Moving Average one 9 v 5.
Trend following systems notoriously make big bucks in large moves but lose money in trend-less, range-bound markets — like the one being zoomed into.
If the Moving Median Crossover system is more active in these sort of markets it will generate more losing trades while capturing similar big winners to the Moving Average Crossover system. Intuitively, it could be hypothesized that the Moving Average evolves in a smoother manner and will generate smoother curves with less erratic moves and consequently less losing trades during trend-less markets — while the Moving Median does not generate a significant edge in detecting large trends.
One test is hardly enough to provide siginificant evidence, however this should give us some insights in the nature of the Moving Median indicator. The first insights being no increase in robustness and a drop in performance when comparing total returns.
The opposite is Mediocristan: No single observation can meaningfully affect the aggregate e. The bell curve is grounded in Mediocristan. There is a qualitative difference between Gaussians and scalable laws, much like gas and water.EFFECTS OF MOTIVATION ON EMPLOYEE PERFORMANCE: A CASE STUDY OF GHANA COMMERCIAL BANK, KUMASI ZONE.

other organizations, was facing resource challenges and implemented numerous strategies, one of which was a performance management system (Aguinis, ). The calculation confirms the under-performance of the Moving Median Crossover system. What about robustness you ask? Well, the Moving Median still scores worse than the Moving Average on both measures of uniformity/dispersion: the standard Coefficient of Variation ( v ) and its alternative cousin based on Median and Median Absolute Deviation ( v ): The Moving Average System.
