Table 3 Parameters used in the analysis of the results

From: An assessment on epitope prediction methods for protozoa genomes

Parameter

Brief description

Formula

Sensitivity (Sn)

The proportion of correctly predicted binders

(a/(a + c))*100

Specificity (Sp)

The proportion of correctly predicted non-binders

(d/(b + d))*100

Positive Predictive Value (PPV)

The probability that a predicted binder will actually be a binder

(a/(a + b))*100

Negative Predictive Value (NPV)

The probability that a predicted non-binder will actually be a non-binder

(d/(c + d))*100

Accuracy

The proportion of correctly predicted peptides (both binders and non-binders)

((a + d)/(a+b+c+d)*100

  1. a = True positive observations.
  2. b = False positive observations.
  3. c = False negative observations.
  4. d = True negative observations.
