Claim One:
1. A medical analytics method implemented on a computer for diagnosing at least one disease (i) afflicting a patient based on clinical data (m) that excludes subjective qualities of said clinical data (m) and prevalence of said at least one disease (i), said method comprising: a) compiling a knowledge base of disease (i) models exhibiting said clinical data (m); b) inputting clinical data present (j) in said patient into said computer; c) matching said clinical data present (j) with said clinical data (m) in said knowledge base; d) composing a differential diagnosis list of ruled in diagnoses (k) for each of said disease (i) models exhibiting at least one clinical datum (m) matching at least one clinical datum present (j); e) computing a probability P(k) for each of said ruled in diagnoses (k) by a mini-max procedure comprising: 1) obtaining sensitivities S(i) m of each of said clinical data (m) for diseases (i) based on disease (i) models that comprise a total number of disease (i) cases: S ( i ) m = number of disease ( i ) cases manifesting clinical datum ( m ) total number of disease ( i ) cases ; 2) computing positive predictive values PP(k) j for clinical data present (j) supporting each of said ruled in diagnoses (k) as follows: PP ( k ) j = S ( k ) j S ( 1 ) j + … + S ( k ) j + … + S ( n ) j , where S(k) j are sensitivities of each clinical datum present (j) to said diagnoses (k), and n is the number of said ruled in diagnoses (k); 3) assigning as probability P(k) of each ruled in diagnosis (k) the maximum value among said positive predictive values PP(k) 1 through PP(k) z : 
 P ( k )=max( PP ( k ) 1 , PP ( k ) 2 ,. .. , PP ( k ) 2 ), where z is the number of said ruled in diagnoses (j); and f) displaying said differential diagnosis list and said probability P(k) for each diagnosis (k) on a display for medical analytics.
