setNLLSWeights: setNLLSWeights

In tbep-tech/tbepRSparrow: RSPARROW: An R system for SPARROW modeling

Description

Assigns the user-defined weights to the system variable 'weight', used to execute a weighted NLLS model estimation. Also calculates the variable 'tiarea' (sum of the incremental drainage area of reaches located between monitoring sites), used to calculate weighting expressions based on the size of the intervening areas between sites.

Executed By: startModelRun.R
Executes Routines:

• assignIncremSiteIDs.R

• errorOccurred.R

• named.list.R

• unPackList.R

Usage

setNLLSWeights(NLLS_weights, run_id, subdata, sitedata, data_names,
  minimum_reaches_separating_sites, batch_mode)

Arguments

NLLS_weights	character string control setting to select regression weights
run_id	character string control setting indicating the current model name
subdata	data.frame input data (subdata)
sitedata	Sites selected for calibration using subdata[(subdata$depvar > 0), ]
data_names	data.frame of variable metadata from data_Dictionary.csv file
minimum_reaches_separating_sites	number indicating the minimum number of reaches separating sites
batch_mode	yes/no character string indicating whether RSPARROW is being run in batch mode

Value

Csites.weights.list regression weights as proportional to incremental area size
