GoogMeter (www.googmeter.com)

GoogMeter : Output


6

GoogMeter : Calculation of Indexes

Totals of #Pages Found: by columns -    Tot(Obj)  

by rows -    Tot(Prop)   

overall - Tot   

Empirical probabilities:   p(Obj) = Tot(Obj) /Tot

p(Prop) = Tot(Prop) /Tot

Expected number of pages:

  E(Obj, Prop) = Tot * p(Obj) * P(Prop)

Indexes: Ind(Obj, Prop) = 100 * N(Obj, Prop) / E(Obj, Prop)


7

GoogMeter : Too variants for bubble's volumes:

Volume    ~    ( N - E )2 / E

2. Volume   ~    | ln ( Ind / 100 ) | = | ln ( N / E ) |
