seawaveQ (version 1.0.0)

fitMod: Internal function that fits the seawaveQ model.

Description

fitMod is called from within fitswavecav but can be invoked directly. It fits the seawaveQ model and returns the results.

Usage

fitMod(cdatsub, cavdat, yrstart, yrend, tndbeg, tndend,
    tanm, pnames, qwcols, mclass = 1)

Arguments

cdatsub

is the concentration data

cavdat

is the continuous (daily) ancillary data

yrstart

is the starting year of the analysis (treated as January 1 of that year).

yrend

is the ending year of the analysis (treated as December 31 of that year).

tndbeg

is the beginning (in whole or decimal years) of the trend period.

tndend

is the end (in whole or decimal years) of the trend period.

tanm

is a character identifier that names the trend analysis run. It is used to label output files.

pnames

is the parameter (water-quality constituents) to analyze (if using USGS parameters, omit the the starting 'P', such as "00945" for sulfate).

qwcols

is a character vector with the beginning of the column headers for remarks code (default is R), and beginning of column headers for concentration data (default is P for parameter).

mclass

has not been implemented yet, but will provide additional model options.

Value

• a pdf file containing plots (see seawaveQPlots), a text file showing the best model survival regression call and results, and a list. The first element of the list contains information about the data and the model(s) selected (see examplestpars). The second element of the list contains the summary of the survival regression call. The third element of the list is itself a list containing the observed concentrations (censored and uncensored) and the predicted concentrations used by seawaveQPlots to generate the plots.
