qc_outliers_subs: Outliers substitution

In sapfluxnet/sapfluxnetQC1: Package with functions related to sapfluxnet project data

Description

Outlier substitution by different methods

Usage

qc_out_tukeyline(y, k = 25L, parent_logger = "test")

qc_out_medianreg(y, k = 25L, parent_logger = "test")

qc_out_median(y, k = 25L, parent_logger = "test")

Arguments

y	vector of values for outlier substitution
k	window semi-value (integer) for substitution value calculation. See details.

Details

k is the semi-value of the desired window for substitute value calculation. The window is formed by the range y[i] - k : y[i] + k.

Value

a vector of the same lengh of y with the outlier values substituted by the calculated value

Functions

out_tukeyline

out_tukeyline performs a robust fitting with the line function

out_medianreg
