conpowerlaw.stat: Continuous Power-Law Scan Statistic

Description

The continuous power law scan statistic evaluate the statistic which compare the node attribute within the subgraph with that outside the subgraph while the node attribute follows the continuous power-law distribution.

Usage

conpowerlaw.stat(obs, pop = 1, zloc, xmin = 1, zetatable = NULL)

Arguments

obs

Numeric vector of observation values.

pop

Numeric vector of population values; default = 1.

zloc

Numeric vector of selected nodes.

xmin

The minmum value of power law distribution; defaut=1.

zetatable

When xmin=1, set up the data(zetatable).

Value

Three values will be returned. The first value is test statistic. The second is the estimated means which estimated outside the selected nodes. The third is the estimated means estimated within the selected nodes.
