Models for analyzing data in initiation-promotion studies.
The objective of this paper is to construct a class of models for analyzing data in initiation-promotion (IP) studies. After the application of an initiator in animals IP studies, histochemical and/or histopathologic criteria are used to define the foci that are postulated to be the origin of tumors. Thus, the dynamics of foci growth are of inherent interest in the study of the mechanism of car...

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولPromotion of callus initiation, shoot regeneration and proliferation in Lisianthus.
The effects of plant growth regulators were examined in order to optimize the callus induction, regeneration, and proliferation of lisianthus (Eustoma grandiflorum). In vitro leaves provided the explants for callus induction. Explants were cultured on Murashige and Skoog (MS) medium with different concentrations of indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and 2,4-dichlorophen...
متن کاملTransition Models for Analyzing Longitudinal Data with Bivariate Mixed Ordinal and Nominal Responses
In many longitudinal studies, nominal and ordinal mixed bivariate responses are measured. In these studies, the aim is to investigate the effects of explanatory variables on these time-related responses. A regression analysis for these types of data must allow for the correlation among responses during the time. To analyze such ordinal-nominal responses, using a proposed weighting approach, an ...
متن کاملPromotion in Smoking Initiation
Causation can never be proven beyond question. The strongest evidence for causality comes from controlled experiments in which individuals are randomly assigned either to a group that will receive exposure to the causal agent—in this case, cigarette advertising—or to one or more control groups that are not exposed to the causal agent, but are identical to the exposure group in every other way. ...
