In probability theory, the Law of Large Numbers is a mathematical law that states that the average of the results obtained from a large number of independent random samples converges to the true value, if it exists. In general, this theorem says that if you repeat the same random experiment many times under the same conditions, the sample average will get closer and closer to the true mean (also called the population mean). https://saulogil.netlify.app/blog/2025-28-09-hospitalization-pa/ Sun, 28 Sep 2025 00:00:00 +0000 https://saulogil.netlify.app/blog/2025-28-09-hospitalization-pa/ The Hidden Link Between Physical Disability and Hospitalizations in Older Adults Increase in the Older Adult Population👴 Global population aging is accelerating, bringing significant challenges for public health. Current estimates predict that by 2030, one in every six people worldwide will be 60 years or older, and by 2050, this group will exceed 2 billion individuals. This demographic shift poses unprecedented economic, cultural, medical, social, and policy challenges, as older adults are more susceptible to multiple comorbidities, chronic diseases, and functional limitations https://saulogil.netlify.app/blog/2024-07-14-decision-tree/ Sun, 14 Jul 2024 00:00:00 +0000 https://saulogil.netlify.app/blog/2024-07-14-decision-tree/ 📒 What is Decision Tree❓ A decision tree is a popular machine learning model used for both classification and regression tasks. It’s called a decision tree because it breaks down a dataset into smaller subsets while developing an increasingly detailed decision-making process resembling a tree’s structure.

However, all too often, we find ourselves subjected to boring slides that fail to captivate or communicate effectively. Moreover, this task takes a long time⌚and, for many people, it is a boring task. But, now, leveraging a Language Model like ChatGPT to create PowerPoint slides can be a game-changer in terms of efficiency and creativity. 🧐Here’s how: Step 1 - Create a script: Open http://chat. https://saulogil.netlify.app/blog/2024-16-02-gender-equity/ Fri, 16 Feb 2024 00:00:00 +0000 https://saulogil.netlify.app/blog/2024-16-02-gender-equity/ Health Equity: Who Are Hospital Rooms And Beds For In Brazil? Sustainable development refers to a global effort that involves development capable of meeting the needs of the current generation without compromising the ability to meet the needs of future generations. This concept is broad and aims at the environmental, economic, and social development of all societies. To achieve this, seventeen goals have been created in an attempt to guide sustainable development objectives. https://saulogil.netlify.app/blog/2024-10-02-seaborn-plot/ Wed, 07 Feb 2024 00:00:00 +0000 https://saulogil.netlify.app/blog/2024-10-02-seaborn-plot/ Commonly Plots with Seaborn (Python) Data visualization is the graphical representation of data and information. It involves the creation of visual elements such as charts, graphs, maps, and dashboards to communicate complex data sets in a more understandable and insightful manner. Data visualization enables users to analyze, interpret, and understand patterns, trends, and relationships within data more effectively than they could through raw numbers or text alone. The primary goals of data visualization include: https://saulogil.netlify.app/blog/2023-10-01-volcano-plot/ Sun, 01 Oct 2023 00:00:00 +0000 https://saulogil.netlify.app/blog/2023-10-01-volcano-plot/ Volcano Plot with R What’s that for?? A volcano plot is a type of scatter-plot that is used to identify changes in large data sets. It is very used by bioinformatic researches when analyzing data from “omics” technologies (e.g., genomics, proteomics, metabolomics, metagenomics, phenomics and transcriptomics). It plots significance versus fold-change on the y and x axes, respectively. It enables quick visual identification of genes with large fold changes that are also statistically significant. https://saulogil.netlify.app/blog/2023-04-10-binary-search/ Mon, 10 Apr 2023 00:00:00 +0000 https://saulogil.netlify.app/blog/2023-04-10-binary-search/ Binary Search Algorithm What’s that for?? Suppose you are looking for a word in a dictionary beginning with the letter R. Although you may look the page-by-page from the letter A to R, it is unlikely you do it, probably you will go to the middle of the dictionary in order to save time. Then, imagine you want to search for an e-mail in a large list of e-mails. The first letter of the e-mail is K. https://saulogil.netlify.app/blog/2023-03-28-regression-models/ Sun, 09 Apr 2023 00:00:00 +0000 https://saulogil.netlify.app/blog/2023-03-28-regression-models/ Regression models for quantitative outcomes What should I use? It is not uncommon situations in which we want to predict something. For issues in which we want to predict quantitative outcomes such as the price of a house in a specific area, which media are associated with sales, if is there a relationship between advertising budget and sales or the price of product, regression models may a useful tool to make this forecast task. https://saulogil.netlify.app/blog/2023-01-05-cost-covid/ Fri, 06 Jan 2023 00:00:00 +0000 https://saulogil.netlify.app/blog/2023-01-05-cost-covid/ What did we do? There is no doubt that pandemic of the COVID-19 has haunted the world due to very large number of hospitalizations, and deaths. Past 2 years, the acute complications of the COVID-19 is controlled around the world due to large scale vaccination, but another issue related to this disease has taken attentions that is the elevated frequency of persistent symptoms in survivors of COVID-19 such as fatigue, weakness, dyspnea, decline in quality of life. https://saulogil.netlify.app/blog/2022-06-22-inactivity-covid/ Wed, 22 Jun 2022 00:00:00 +0000 https://saulogil.netlify.app/blog/2022-06-22-inactivity-covid/ The pandemic of the coronavirus disease 2019 (COVID-19) has caused morbidity and mortality at an unprecedented global scale with millions of confirmed cases, hospitalizations, and deaths. Fortunately, with vaccination, the cases requiring hospitalization and deaths dramatically decreased, but a new issue arising from COVID-19 making focus, which is the elevated prevalence of persistent symptoms, named long-COVID, such as fatigue, weakness, dyspnea, decline in quality of life among others. The list of persistent symptoms is very wide as we can observe in the below figure. https://saulogil.netlify.app/blog/2022-04-30-first-post/ Sat, 30 Apr 2022 00:00:00 +0000 https://saulogil.netlify.app/blog/2022-04-30-first-post/ Who am I❓ What do I do❓ I spent time thinking what about my first post could be and, finally, I decided that it would be about me!
