sens_slope: Pre-withened nonlinear Sen´s slope.

In ERottler/alptempr: Statistical analysis of alpine climatological data

Description

Calculation of nonlinear pre-whitened Theil-Sen´s slope using zyp.trend.vector. To remove lag-1 autocorrelation, the input series is pre-withened using the Zhang approach. Trend magnitude only is calculated when percentage of NAs in input vector does not exceed a pre-defined threshold.

Usage

sens_slope(data_in, cover_thresh = 0.9)

Arguments

data_in	vector of input data
cover_thresh	Trend only calculated when percentage of NAs in input vector does not exceed cover_thresh (0-1)

Value

Nonlinear pre-withened Theil-Sen´s slope.

Examples

data_slope <- c(2, 3, 5, 6 ,8, 5, 8, 12, NA, NA)
sens_slope(data_in, cover_thresh = 0.5)
sens_slope(data_in, cover_thresh = 0.9)
