Functions

func CategoryToDist

func CategoryToDist(cat string) relational.Degree

CategoryToDist converts the category used by ML-Relate to its relational distance. Errors on unrecognized categories.

func Normalize

func Normalize(vals []float64) []float64

Normalize adjusts the distribution of values to be bounded in [0,1]

func RelToLevel

func RelToLevel(x float64) relational.Degree

RelToLevel computes the relational distance given the relatedness score

Examples:

    relToLevel(0.5)   --> First
    relToLevel(0.25)  --> Second
    relToLevel(0.125) --> Third
	   ...
    relToLevel(<=0)   --> Unrelated

func RmHeader

func RmHeader(records [][]string) [][]string

RmHeader removes the header row of a table TODO: Make checks for header content before removal

func RmZeros

func RmZeros(vals []float64) []float64

RmZeros removes negatives as unrelated (i.e., 0)

func StringInSlice

func StringInSlice(str string, list []string) bool
