Krackhardt and Stern’s E-I Index (ei_index)

Description

Linear transformation of the proportion homophilous measure (Krackhardt and Stern 1988; Perry et al. 2018)

Usage

ei_index(
  ego_id,
  ego_measure,
  alter_ego,
  alter_measure,
  prefix = NULL,
  suffix = NULL
)

Arguments

ego_id	A vector of unique ego identifiers located in an ego dataframe. If using data objects created by ego_netwrite, this should be the data frame entitled egos.
ego_measure	A vector of attributes corresponding to each ego
alter_ego	A vector of ego identifiers located in an alter dataframe. If using data objects created by ego_netwrite, this should be the data frame entitled alters.
alter_measure	A vector of attributes corresponding to each alter
prefix	A character value indicating the desired prefix for the calculated E-I measure
suffix	A character value indicating the desired suffix for the calculated E-I measure

Value

ei_index returns a dataframe of vectors that include the ego identifier and the ei-index value for the selected attribute

Examples

# Run `ego_netwrite`
ngq_nw <- ego_netwrite(egos = ngq_egos,
                      ego_id = ngq_egos$ego_id,

                      alters = ngq_alters,
                      alter_id = ngq_alters$alter_id,
                      alter_ego = ngq_alters$ego_id,

                      max_alters = 10,
                      alter_alter = ngq_aa,
                      aa_ego = ngq_aa$ego_id,
                      i_elements = ngq_aa$alter1,
                      j_elements = ngq_aa$alter2,
                      directed = FALSE)


# Calculate E-I Index for Race
race_ei <- ei_index(ego_id = ngq_nw$egos$ego_id, ego_measure = ngq_nw$egos$race,
                   alter_ego = ngq_nw$alters$ego_id, alter_measure = ngq_nw$alters$race,
                   prefix = "race")
