gamma_conv_msteps: Gamma convergence iterated on several years in pairs

Description

Given a dataframe (tibble) of sorted times by countries indicator, the gamma convergence is calculated between pairs of subsequent years. A time index is required. Missing values are not allowed.

Usage

gamma_conv_msteps(rawDat, startTime, endTime, timeName = "time")

Value

dataset of gamma values (indicated as KIt in Eurofound 2018 paper).

Arguments

rawDat

the tibble made by times and countries.

startTime

the first year to consider, included.

endTime

the last year to consider, included.

timeName

the name of the variable that contains time information.

Examples

# Example 1
# Dataframe in the format time by countries:
require(tibble)
myTB  <- tibble::tribble(
~time, ~UK, ~DE, ~IT,
 1988,   1201, 868, 578,
 1989,   1150, 978, 682,
 1990,   998,  1250, 332,
 1991,  1600,  1350, 802
 )
 resGammaST <- gamma_conv_msteps(myTB,startTime = 1988,endTime=1991, timeName = "time")

# Example 2
# Gamma convergence iterated for several pairs of years for the emp_20_64_MS Eurofound dataset
data("emp_20_64_MS")
# check name of the time variable
names(emp_20_64_MS)
resGammaST2<-gamma_conv_msteps(emp_20_64_MS,startTime=2002,endTime=2006, timeName = "time")
resGammaST3<-gamma_conv_msteps(emp_20_64_MS,startTime=2002,endTime=2018, timeName = "time")
resGammaST4<-gamma_conv_msteps(emp_20_64_MS,startTime=2007,endTime=2012, timeName = "time")
