## BioPHP - Minitools for stats

Describe data

Will compute Mean, Median, Mode, Minimum, Maximum, Range, Sum x, Sum x2,
Variance, Standard Deviation, Skewness and Kurtosis from input values.
Some statiticals are described.
Discriminatory Power

Computes discriminatory poweras described by Hunter.
Linear Correlation and Regresion Curve

Will calculate a lineal relation ship between x and y values by solving a
and b values at y=ax+b. Correlation coeficient will be computed (r)
Sensibility and Specificity of diagnostic tets

Computes Sensitivity, Specificity, Positive Predictive Value, Negative
Predictive Value,Positive Likelihood Ratio and Negative Likelihood Ratio .
