summary.etasclass: Summary method for etasclass objects

In etasFLP: Mixed FLP and ML Estimation of ETAS Space-Time Point Processes for Earthquake Description

Summary method for etasclass objects

Description

This is the main method to summarize the output of an object of class etasclass.

It gives some information on the execution and gives estimates of the ETAS parameters together with the standard errors.

More detailed output is avaliable by inspecting str(etasclass.object), and printing single objects.

Usage

## S3 method for class 'etasclass'
summary(object,full=FALSE,...)

Arguments

object	an etaclass object to pass to summary.
full	logical. New in version 2.2. If TRUE the full original call will be displayed together with some more output.
...	other arguments.

Details

Displays summary information about an object of class etasclass.

Value

Displays AIC values, parameters estimates and their standard errors, together with some information on the execution of the etasclass estimation process. Displays also the exact call of the function that generated etasclass
