The Statistical Methods Manual documents statistical analysis methods applicable
to data collected by the Environmental Monitoring and Assessment Program
(EMAP). The methods described give the procedures to estimate the current
status of ecological resources that are appropriate for survey designs
implemented by EMAP. The methods apply to analyses of EMAP regional
demonstration studies and R-EMAP studies. Sufficient information is given to
enable a user to determine if the method is appropriate for the survey design
used in these procedures or to cover additional EMAP or R-EMAP studies. The
audience for the manual are statisticians or scientists with a reasonable
background in statistics. The calculations are detailed so that a scientific
programmer can implement the methods.
