Summary function for objects of class gamMRSea.power

Usage

# S3 method for class 'gamMRSea.power'
summary(power.object, null.object = NULL, truebeta = NULL)

Arguments

power.object: An object of class gamMRSea.power
null.object: Object containing information regarding the error rate when no change is present in the data.
truebeta: Value indicating the proportion of data affected by the change. Only required for a site wide change.

Value

printed summary output

If only the power.object is provided, then the summary is reduced or informs the reader of some unknowns.

# Load two power objects that were created with a 20% sitewide decline
# 50 simulations were run
data(nysted.power.oc)
data(nysted.power.oc.null)

summary(nysted.power.oc, nysted.power.oc.null, truebeta=log(0.8))
