Fuzzy.exact.variance {FuzzySTs}

Calculates the exact variance

Description

Calculates the exact variance

Usage

Fuzzy.exact.variance(data.fuzzified, breakpoints = 100, plot = FALSE)

Arguments

data.fuzzified

a fuzzification matrix constructed by a call to the function FUZZ or the function GFUZZ, or a similar matrix. No NA are allowed.

breakpoints

a positive arbitrary integer representing the number of breaks chosen to build the numerical alpha-cuts. It is fixed to 100 by default.

plot

fixed by default to "FALSE". plot="TRUE" if a plot of the fuzzy number is required.

Value

The numerical alpha-cuts of the estimated fuzzy variance.
