devRate (version 0.2.4)

devRateQlStat: Statistical indices of the nls goodness-of-fit

Description

Return a table of multiple statistical indices of goodness-of-fit

Usage

devRateQlStat(nlsDR)

Value

A data.frame with statistical indices in columns (RSS, RMSE, AIC, BIC) and nls objects in rows.

Arguments

nlsDR

A list of nls objects.

Details

NULL is returned when nlsDR is not of type list. AIC and BIC are calculated using the RSS (Burnham and Anderson, 2002).

Examples

myDf <- data.frame(
  temp = seq(from = 0, to = 50, by = 10),
  rT = c(0.001, 0.008, 0.02, 0.03, 0.018, 0.004))
damos_08Fit <- devRateModel(
  eq = damos_08,
  dfData = myDf,
  startValues = list(aa = 1, bb = 1, cc = 1),
  algo = "LM")
kontodimas_04Fit <- devRateModel(
  eq = kontodimas_04,
  dfData = myDf,
  startValues = list(aa = 1, Tmin = 7, Tmax = 40),
  algo = "LM")
poly2Fit <- devRateModel(
  eq = poly2,
  dfData = myDf,
  startValues = list(a0 = 1, a1 = 1, a2 = 1),
  algo = "LM")
devRateQlStat(
  nlsDR = list(damos_08Fit, kontodimas_04Fit, poly2Fit)
)
