optimise_sinus_variablePeriod: Optimise Sinus Fit for Variable Period

In KWB-R/kwb.heatsine: R Package for Calculating Hydraulic Travel Times Based on Sinus Temperature Fitting

Description

Optimise Sinus Fit for Variable Period

Usage

optimise_sinus_variablePeriod(
  temp_df,
  optFunc = opt_func,
  opt_limits = c(100, 500),
  opt_tolerance = 0.001,
  opt_debug = FALSE
)

Arguments

temp_df	data frame with temperature data and columns "date" (YYYY-MM-DD) and "value"
optFunc	optimisation function (default: opt_func )
opt_limits	optimisation limits for "period_length" (default: c(100,500))
opt_tolerance	(default: 0.001)
opt_debug	show debug information (default: FALSE)

Value

list with fit parameters ("paras"), goodness-of-fit values ("gof"), special points, i.e. min/max/turning-points ("points), fit model ("lm_model") and input data ("data")
