ccdcTimeSeries: Implementation of CCDC for time series data

In dulvrq/ddl8s1ts: Map forest disturbance using Landsat 8 and Sentinel-1

Description

Implementation of CCDC fitting and variable deriviation for time series Landsat data.

Usage

ccdcTimeSeries(
  values,
  VI = "NBR",
  startDOY = 2016,
  fillNA = F,
  init_rirls,
  rirls,
  ccdc,
  init_ccdc,
  rmse
)

Arguments
