parsec-package: PARtial orders in Socio-EConomics

Description Details Author(s) Examples

Description

The package implements basic partial order tools for multidimensional poverty evaluation with ordinal variables. Its main goal is to provide socio-economic scholars with an integrated set of elementary functions for multidimensional poverty evaluation, based on ordinal information. The package is organized in four main parts. The first two comprise functions for data management and basic partial order analysis; the third and the fourth are devoted to evaluation and implement both the poset-based approach and a more classical counting procedure.

# a simple example of package application to obtain first poset-based results

# definition of the variables by their number of modalities
variables <- c(2, 2, 2)

# definition of the threshold
threshold <- c("112", "211")

# extraction of all the possible profiles by the variables definition, the
# function returns an object of class "wprof", weighted profiles, by default,
# the wheigths/frequencies are set equal to 1
profiles <- var2prof(varlen = variables)

# the following function creates the matrices that describe the poset, and
# provide all the results related to it
eval <- evaluation(profiles, threshold, nit = 10^5, maxint = 10^3)

# the results can be summarized, the method returns a data.frame object that
# describes the profiles and you can also summarize
summary(summary(eval))

# a method of the plot function returns the Hasse diagram, a frequency 
# distribution of the threshold, the identification function, the rank
# distribution of each profile through a barplot, and the relative gap.
