Correlation table for Active and Passive throughput calculations

Correlation table for Active and Passive throughput calculations
I-Heng Mei, Les Cottrell, and Connie Logg
Updated: Mon Aug 26 16:00:42 PDT 2002

Throughput was calculated in 3 ways:

method1: SUM( MBits_s/Time_s )

method2: SUM( MBits_s)/AVG(Time_s)

method3: SUM( MBits_s)/MAX(Time_s)

R is the correlation coefficient. The Correlation Coefficient R is defined as:
R = COV(x,y) / (Std(x) * Std(y)), where:
COV(x,y) = (1/(n-1)) * SUM((x_i-Avg(x))*(y_i-Avg(y))), is the covariance,
and the SUM is over the n paired Samples (i=1..n) , also
Avg(x) = (1/n)) * SUM(x_i)) and Avg(y) = (1/n) * SUM(y_i)) are the averages, and
Std(x) = sqrt((1/(n-1)) * SUM((x_i-xm)²)) and Std(y) = sqrt((1/(n-1)) * SUM((y_i-ym)²)). are the standard deviations.
Error is given by Error = (Avg(x) - Avg(y)) / Avg(x)

See the summary statistics for aggregate and distribution information.
Rows with alarming values (such as R ≤ .6, error ≥ .1) are shaded in dark yellow. The values are highlighted in bright yellow
