 Colostrum contains antibodies that have an impact on improving the baby's body resistance so any infections enter gastrointestinal tract can be addressed properly. This study aims to determine effect of resources and family support post partum mothers against giving colostrum newborn in hospitals Indrasari Indragiri Hulu. research is analytic with cross sectional approach. Data were coll...
It is often believed that de Finetti’s coherence principle naturally leads, in the finite case, to the Kolmogorov’s probability theory of random phenomena, which then implies Bell’s inequality. Thus, not only a violation of Bell’s inequality looks paradoxical in the Kolmogorovian framework, but it should violate also de Finetti’s coherence principle. Firstly, we show that this is not the case: ...
Results: In this study, the following pattern of ABO blood groups was observed in IHD patients : blood group A 251 (27.67%); blood group B 329 (36.27%); blood group O 235 (25.91%); blood group AB 92 (10.14%). We found no relationship of ABO blood groups with age (p-value = 0.234), gender (p-value = 0.093), hypertension (p-value = 0.230), diabetes mellitus (p-value = 0.801), family history of IH...
We describe an approach for filtering phrase tables in a Statistical Machine Translation system, which relies on a statistical independence measure called Noise, first introduced in (Moore, 2004). While previous work by (Johnson et al., 2007) also addressed the question of phrase table filtering, it relied on a simpler independence measure, the p-value, which is theoretically less satisfying th...
مقدمه: منابع انرژی یکی از مهم ترین منابع خدمت رسانی در بیمارستان به شمار می آید. هدف از این پژوهش مقایسه ی میزان مصرف انرژی قبل و پس از اجرای طرح هدفمندی یارانه ها در بیمارستان های دانشگاه علوم پزشکی قزوین در سال های 1390-1388 بود. روش بررسی: این پژوهش کاربردی از دسته مطالعات تحلیلی- مقطعی است که در سال 1390 انجام شد. جامعه ی پژوهش شامل کلیه ی بیمارستان های دانشگاه علوم پزشکی قزوین(5 بیمارستان)...
مقدمه: امروزه، با ظهور پرونده ی الکترونیکی بیمار، نیاز به تبادل اطلاعات افزایش یافته و در نتیجه امنیت و محرمانگی در سیستم های اطلاعاتی باید بیش تر مورد توجه قرار گیرد. در پژوهش حاضر، وضعیت امنیت اطلاعات از سه بعد مدیریتی، فنی و فیزیکی در سیستم های اطلاعات بیمارستانی بیمارستان های وابسته به دانشگاه های علوم پزشکی تهران و شهید بهشتی مورد بررسی قرار گرفت. روش بررسی: این پژوهش از نوع کاربردی بود که...
In stat ist ics, a likelihood rat io test is a stat ist ical test used to compare the f it of two models, one of which (the null model) is a special case of the other (the alternative model). The test is based on the likelihood rat io, which expresses how many t imes more likely the data are under one model than the other. This likelihood rat io, or equivalent ly its logarithm, can then be used...
Abstract: When it is necessary to approximate a small permutation pvalue p, then simulation is very costly. For linear statistics, a Gaussian approximation p̂1 reduces to the volume of a spherical cap. Using Stolarsky’s (1973) invariance principle from discrepancy theory, we get a formula for the mean of (p̂1− p)2 over all spherical caps. From a theorem of Brauchart and Dick (2013) we get such a ...
Much of science is (rightly or wrongly) driven by hypothesis testing. Even in situations where the hypothesis testing paradigm is correct, the common practice of basing inferences solely on p-values has been under intense criticism for over 50 years. We propose, as an alternative, the use of the odds of a correct rejection of the null hypothesis to incorrect rejection. Both pre-experimental ver...
This work studies multiple hypothesis testing in the setting when we obtain data sequentially and may choose when to stop sampling. We summarize the notion of a sequential pvalue (one that can be continually updated and still maintain a type I error guarantee) and provide several examples from the literature. This tool allows us to convert fixedhorizon step-up or step-down multiple hypothesis t...
