[amibroker] K-Ratio Implementation (revisited)

["Ron Rowland" <rowland@xxxxxxxx>]

I made two posts on this subject a couple of weeks ago, but it seems 
those posts have disappeared.

Anyway.  I am now able to duplicate the AmiBroker 4.96 beta CBT results 
for K-Ratio.  My implmentation follows and appears to match the 
AmiBroker results for backtest periods lasting from 2 months to 17+ 
years.

Eq = Foreign("~~~EQUITY", "C");	// Assign Close of Backtest Equity = Eq
n  = Barcount -1; // Number of periods

// K-Ratio - only valid for non-compounding systems
EqLRS = LinRegSlope(Eq, n+1); // Linear Reg Slope of entire (n+1) range
EqSE  = StdErr(Eq, n+1);// Std Err of entire (n+1) range 
EqKR  = EqLRS/EqSE;    // K-Ratio (unitless measure)
EqKRAmi	= EqKR*sqrt(n+1)/sqrt(12);// AmiBroker 4.96 implementation

My question is:  Why does it require a divide by sqrt(12) to work?
