If X is a discrete random variable taking values x in the non-negative integers {0,1, ...}, then the probability generating function of X is defined as [1] = = = (), where is the probability mass function of .
Pengrowth Energy Corporation was a Canadian oil and natural gas company based in Calgary, Alberta.Established in 1988 by Calgary entrepreneur James S Kinnear, it was one of the largest of the Canadian royalty trusts ("Canroys"), with a market capitalization of US$4.12 billion at the end of 2007.
Platelet-derived growth factor (PDGF) is one among numerous growth factors that regulate cell growth and division.In particular, PDGF plays a significant role in blood vessel formation, the growth of blood vessels from already-existing blood vessel tissue, mitogenesis, i.e. proliferation, of mesenchymal cells such as fibroblasts, osteoblasts, tenocytes, vascular smooth muscle cells and ...
Placental growth factor (PlGF) is a protein that in humans is encoded by the PGF gene. [5] [6] Placental growth factor (PGF) is a member of the VEGF (vascular endothelial growth factor) sub-family - a key molecule in angiogenesis and vasculogenesis, in particular during embryogenesis. The main source of PGF during pregnancy is the placental ...
Paterson GlobalFoods (PGF) is a family-owned international agri-food conglomerate. It was established in 1908 as the N. M. Paterson and Company. [1]
Prostaglandin F 2α (PGF 2α in prostanoid nomenclature), pharmaceutically termed dinoprost, is a naturally occurring prostaglandin used in medicine to induce labor and as an abortifacient. [1] Prostaglandins are lipids throughout the entire body that have a hormone-like function. [ 2 ]
The Dirichlet distribution is a conjugate distribution to the multinomial distribution. This fact leads to an analytically tractable compound distribution.For a random vector of category counts = (, …,), distributed according to a multinomial distribution, the marginal distribution is obtained by integrating on the distribution for p which can be thought of as a random vector following a ...
The dividends are then taxed as personal income. This system, similar to real estate investment trusts , effectively avoids the double taxation of corporate income. Texas oilman T. Boone Pickens is often credited with creating the first royalty trust in 1979; however Marine Petroleum Trust (Marps) was created in 1956, twenty three years earlier.
