Utility Function for Printing netdx Object

Description

Prints basic information and statistics from a netdx object.

Usage

## S3 method for class 'netdx'
print(x, digits = 3, ...)

Arguments

x	an object of class netdx
digits	number of digits to print in statistics tables
...	additional arguments (currently ignored)

Details

Given a netdx object, print.netdx prints the diagnostic method (static/dynamic), number of simulations, and (if dynamic) the number of time steps per simulation used in generating the netdx object, as well as printing the formation statistics table and (if present) the duration and dissolution statistics tables. The statistics tables are interpreted as follows.

Each row has the name of a particular network statistic. In the formation table, these correspond to actual network statistics in the obvious way. In the duration and dissolution tables, these correspond to dissolution model dyad types: in a homogeneous dissolution model, all dyads are of the edges type; in a heterogeneous dissolution model, a dyad with a nonzero nodematch or nodemix change statistic in the dissolution model has type equal to that statistic, and has type equal to edges otherwise. The statistics of interest for the duration and dissolution tables are, respectively, the mean age of extant edges and the edge dissolution rate, broken down by dissolution model dyad type. (The current convention is to treat the mean age and dissolution rate for a particular dissolution dyad type as 0 on time steps with no edges of that type; this behavior may be changed in the future.)

The columns are named Target, Sim Mean, Pct Diff, Sim SE, Z Score, SD(Sim Means), and SD(Statistic). The Sim Mean column refers to the mean statistic value, across all time steps in all simulations in the dynamic case, and across all sampled networks in all simulations in the static case. The Sim SE column refers to the standard error in the mean, estimated using coda::effectiveSize. The Target column indicates the target value (if present) for the statistic, and the Pct Diff column gives (Sim Mean - Target)/Target when Target is present. The Z Score column gives (Sim Mean - Target)/(Sim SE). The SD(Sim Means) column gives the empirical standard deviation across simulations of the mean statistic value within simulation, and SD(Statistic) gives the empirical standard deviation of the statistic value across all the simulated data.
