What distinguishes ourweighting scheme from existing boosting methods isthatwhile the output ofeach weak estimator isamultivariate probability distribution, the data only provides the specific event that occurred and the time of occurrence and thus we introduce new notions of "predictioncorrectness"thatapplyinoursetting.

Nature-inspired metaheuristic algorithms are important components of artificial intelligence, and are increasingly used across disciplines to tackle various types of challenging optimization problems. We apply a newly proposed nature-inspired metaheuristic algorithm called competitive swarm optimizer with mutated agents (CSO-MA) and demonstrate its flexibility and out-performance relative to its competitors in a variety of optimization problems in the statistical sciences. In particular, we show the algorithm is efficient and can incorporate various cost structures or multiple user-specified nonlinear constraints. Our applications include (i) finding maximum likelihood estimates of parameters in a single cell generalized trend model to study pseudotime in bioinformatics, (ii) estimating parameters in a commonly used Rasch model in education research, (iii) finding M-estimates for a Cox regression in a Markov renewal model and (iv) matrix completion to impute missing values in a two compartment model. In addition we discuss applications to (v) select variables optimally in an ecology problem and (vi) design a car refueling experiment for the auto industry using a logistic model with multiple interacting factors.

Our aim is to publish prioritized research from all over the world in terms of global health in the form of oral and summary papers without wasting time.

In parallel with all the developments in technology, we delivered MedicReS 2022 Congress to all our members via MedicReS TV on our www.medicres.club Papers coming to our congress pass through the referee system in MedicReS advisory boards, and oral abstracts are published in English in MedicReS GMR World Congress Abstracts and Congress Proceedings Book. Your oral presentations are also given to you as MP4.

John Quackenbush was frustrated with Google. It was January 2020, and a team led by researchers from Google Health had just published a study in Nature about an artificial intelligence (AI) system they had developed to analyze mammograms for signs of breast cancer. The system didn't just work, according to the study, it worked exceptionally well. When the team fed it two large sets of images to analyze--one from the UK and one from the U.S.--it reduced false positives by 1.2 and 5.7 percent and false negatives by 2.7 and 9.4 percent compared with the original determinations made by medical professionals. In a separate test that pitted the AI system against six board-certified radiologists in analyzing nearly 500 mammograms, the algorithm outperformed each of the specialists. The authors concluded that the system was "capable of surpassing human experts in breast cancer prediction" and ready for clinical trials. An avalanche of buzzy headlines soon followed. "Google AI system can beat doctors at detecting breast cancer," a CNN story declared.

The last few years have seen artificial intelligence (AI) as an ever-evolving and rapidly growing space. It has been vastly adopted across sectors and domains not just to study and analyse data or find hidden patterns but to also make meaningful real-life decisions. The global AI market was worth $35.92 billion in 2020. And according to Fortune Business Insights, the market is expected to grow at a CAGR of 33.6 per cent between 2020 and 2028, to reach a valuation of $360.36 billion in 2028. India itself is expected to invest $1 billion in the AI space by 2023.

Modern bio-technologies have produced a vast amount of high-throughput data with the number of predictors far greater than the sample size. In order to identify more novel biomarkers and understand biological mechanisms, it is vital to detect signals weakly associated with outcomes among ultrahigh-dimensional predictors. However, existing screening methods, which typically ignore correlation information, are likely to miss these weak signals. By incorporating the inter-feature dependence, we propose a covariance-insured screening methodology to identify predictors that are jointly informative but only marginally weakly associated with outcomes. The validity of the method is examined via extensive simulations and real data studies for selecting potential genetic factors related to the onset of cancer.

Biometrics and Biostatistics are disciplines of biological sciences concerned with the application of mathematical-statistical theory, principles, and practices to the observation, measurement, and analysis of biological data and phenomena. Journal of Biometrics and Biostatistics is a leading peer reviewed journal, promoting open access publishing in the collection of major scientific journals available in the scientific society. This promotes the application of statistical methods to the solution of biological problems. Journal of Biometrics and Biostatistics is a academic journal and aims to publish most complete and reliable source of information on the discoveries and current developments in the mode of original articles, review articles, case reports, short communications, etc. in all areas related to Biometrics, Medical statistics and making them freely available through online without any restrictions or any other subscriptions to researchers worldwide. It is an online manuscript submission, review and managing systems.

KG: Starting from the beginning, what is statistics and how did it come about? Could you give us a short definition and history of the discipline? In a brief nutshell statistics began as a way to understand the workings of states, productivity, life expectancy, agricultural yields, etc., and to make estimates of things from samples (an statistical example of the latter dates back to the 5th century BCE in Athens). Concerning a definition for statistics, it is a field that is a science unto itself and that benefits all other fields and everyday life. What is unique about statistics is its proven tools for decision making in the face of uncertainty, understanding sources of variation and bias, and most importantly, statistical thinking.

Laura Hatfield and Sherri Rose are Assistant Professors specializing in biostatistics at Harvard Medical School in the Department of Health Care Policy. Laura received her PhD in Biostatistics from the University of Minnesota and Sherri completed her PhD in Biostatistics at UC Berkeley. They are developing novel statistical methods for health policy problems. Rose: I'd definitely say a statistician. Even when I'm working on things that fall into the categories of data science or machine learning, there's underlying statistical theory guiding that process, be it for methods development or applications.
