As we are discussing the solution to a problem of biostatistical inference it is best to begin by defining the problem. The problem of disputed paternity can be reduced to the following question: Is this man the father of this child, or not?

Transcranial Doppler sonography pulsatility index (PI) reflects intracranial pressure (ICP)
Surgical Neurology, 2004In patients with intracranial pathology, especially when comatose, it is desirable to have knowledge of the intracranial pressure (ICP). To investigate the relationship between ICP and transcranial Doppler (TCD) derived pulsatility index (PI) in neurosurgical patients, a prospective study was performed on patients admitted to our neurointensive care ...

Comparison of the Periodontal Index (PI) and Community Periodontal Index of Treatment Needs (CPITN)
Community Dentistry and Oral Epidemiology, 1986Abstract 692 dental adults in the age ranges, 15‐19, 20‐29, and 35‐44 yr, were assessed for their periodontal conditions and treatment needs using the Periodontal Index (PI) and Community Periodontal Index of Treatment Needs (CPITN). The relative advantages and disadvantages of the two indices were evaluated as epidemiological screening procedures. The

Index cheville-bras et pied diabétique : Un mariage ennuyeux
Annales de Chirurgie Vasculaire, 2011Objectifs L'index cheville-bras (ICB) est un test simple, non invasif, employe couramment qui detecte la maladie arterielle peripherique (MAP). Chez les patients presentant un diabete, l'ICB est notoirement peu fiable et ceci est habituellement attribue a la calcinose mediale, qui raidit les arteres et les rend mediocrement compressibles.

Performance Index for Servo Drives under PI Speed Control
Solid State Phenomena, 2016The paper points out a minimum variance based performance index for restricted controller structure, known in literature and applied in process industries. The theory is introduced briefly. As core of the paper adaption to the topic of speed control for electromechanical drives is shown. Simulational and experimental results for various single and dual-

Computing Vertex PI Index of Tetrathiafulvalene Dendrimers
2010General formulas are obtained for the vertex Padmakar-Ivan index (PIv) of tetrathiafulvalene (TTF) dendrimer, whereby TTF units we are employed as branching centers. The PIv index is a Wiener-Szeged-like index developed very recently. This topological index is defined as the summation of all sums of nu(e) and nv(e), over all edges of connected graph G.

Szeged and vertex PI index of graphs over modules
Summary: If we have a commutative ring \(R\) and it is identified as \(1\neq 0\) there is an \(R\)-module \(M\), \(G_R(M)\) will denote the Scalar product graph of \(M\). Vertices of \(G_R(M)\) are elements of \(M\), and \(a\), \(b\) in \(M\) are adjoining if \(a = rb\) or \(b = ra\) for some \(r\in R\).Nouri Jouybari, Mostafa +1 more
