In convergEU: Monitoring Convergence of EU Countries

Time-indicator serie to straight lines parameters

Description

Given a dataset with first column times and second column the indicator values parameters of time-spliced straight lines are calculated. No checking is performed in input. Time values must differ by a positive constant.

Usage

ts_parlin(dataMat)

Arguments

dataMat

two columns (times, indicator) dataset

Value

dataset(tibble) where each row is (times, intercept, slope)
