Function that performs the Enhanced Standard Analysis.

Description

Function that performs the Enhanced Standard Analysis.

Usage

esa(oldtt, nec_cond, untenable_LR, contrad_rows)

Arguments

oldtt	A truthTable object.
nec_cond	A vector of character strings containing the necessary conditions. Conditions should be capitalized and negated conditions should be inserted with a "~". Unions of conditions are performed with a "+". Using this argument, logical remainder rows that contradict the statement of necessity will not be used in the analysis (i.e. OUT will be set to 0 in the truth table).
untenable_LR	A Boolean expression containing the untenable logical remainders. Conditions should be capitalized and negated conditions should be inserted with a "~". Intersections of conditions are performed with a "*". Using this argument, logical remainder rows containing the particular intersection specified will not be used in the analysis (i.e. OUT will be set to 0 in the truth table).
contrad_rows	A vector containing the names of the rows that are contradictory. Using this argument, all rows with the names specified (both logical remainders and rows containing empirical information) will not be used in the analysis (i.e. OUT will be set to 0 in the truth table).

Value

It returns a new truth table in which all truth table rows are set to outcome value 0 that would otherwise present untenable assumptions.

Examples

# Import your data. For example:

data(SCHF)

# Get the truth table for the presence of the outcome:

TT_y <- truthTable(SCHF, outcome = "EXPORT",
                   conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                   incl.cut = .9,
                   complete = TRUE,
                   PRI = TRUE,
                   sort.by = c("out", "incl", "n"))

# Exclude condition STOCK + MA and condition EMP as necessary for EXPORT
# Exclude all remainder rows containing the combination BARGAIN*~OCCUP
# Exclude the rows "19", "14", "46", "51" as contradictory:

newtt <- esa(oldtt = TT_y, nec_cond = c("STOCK+MA", "EMP"), 
          untenable_LR = "BARGAIN*~OCCUP", contrad_rows = c("19", "14", "46", "51"))

# The truth table newly created can afterwards be used in further analyses
