Biostatistics and Data Science

 


Enabling Successful Research

A major aim of biomedical research at NASA is to acquire data to evaluate, understand, and assess the biomedical hazards of spaceflight and to develop effective countermeasures. The Biostatistics and Data Science (BaDS) team consists of researchers within the Human Health and Performance Directorate who apply methods of statistical science to NASA’s research and biomedical data. Members of the team collaborate with research and operational groups, ensuring their efforts produce results with statistical integrity and follow reproducible research principles. 

Data Science Support

Beyond statistics, the laboratory aids with wrangling and exploring data. Data wrangling includes extracting and transforming data in preparation for analysis and visualization. Data can come in many different formats, the BaDS team helps researchers harmonize (bring data sets together) information across sources. Exploration includes initial analysis and building informative visualizations to deepen the understanding of the evidence. Analyzing and interpreting data to produce insights follow. 

Statistical Consulting Services

The BaDS team provides collaboration and consulting expertise to the Directorate in the application of statistical theory and practice to ongoing biomedical research. Laboratory personnel aid in the preparation of sections of research proposals that deal with experiment design, statistical modeling, and subsequent analysis of anticipated research data. Once data are gathered, BaDS statisticians assist with analysis, visualization, and interpretation of results so that investigators can extract the most information while maintaining statistical integrity. A BaDS statistician may be a co-investigator on a project requiring sophisticated statistical modeling and/or analysis techniques. Through collaboration, members of the BaDS team expand their knowledge base in such diverse medical fields as environmental physiology, osteopathy, neurology, pharmacology, microbiology, cardiology, nutrition, and psychology. To meet the unique data collected by NASA, statisticians may develop new techniques to address challenges such as small sample sizes of ISS studies, missing data, operational constraints, and novel measures of outcome.

Data experts race to preserve US government statistics amid quiet purges

Image
                                                After watching data sets be altered or disappear from U.S. government websites in unprecedented ways after President Donald Trump began his second term, an army of outside statisticians, demographers and computer scientists have joined forces to capture, preserve and share data sets, sometimes clandestinely. "There are trillions of bytes of data files, and I can't even imagine how many public dollars were spent to collect those data. ... But right now, they're sitting someplace that is inaccessible because there are no staff to appropriately manage those data," Jennifer Park, a study director for the Committee on National Statistics, National Academies of Sciences, Engineering, and Medicine, said during the conference hosted by the Association of Public Data Users (APDU). Their goal is to make sure they are available in t...

11 Essential Statistical Tools for Data-Driven Research

Image
  Best Statistical Tools, Statistical analysis is a crucial part of research, and statistical tools can streamline the process by helping researchers interpret the data in a simpler format. Here's the list of best statistical tools. 1. R In data analytics, R stands out among the top open-source statistical tools. Researchers in statistics use it. It provides high-quality toolboxes that can be used for many different things. The learning curve for the open-source programming language R is steep. R programming provides an efficient data handling and storage facility. R also has the best set available for array calculations. Thanks to its graphical tools for analysis, data visualization is another area where R shines. It is an all-inclusive high-level programming language with various functions, conditional loops, and decision expressions 2. Python Python is a versatile language with statistics modules. Its versatility and depth make it an excellent choice for creating analysis pipeli...

Trump Gets Rid of Those Pesky Statistics

Image
  For decades, Donald Trump has been at war with numbers. Some have capitulated more swiftly than others. His weight, his golf scores, and his net worth have long fallen in line. As I understand it, a Trump doctor appointment consists of going to a medical professional and announcing how much you would like to weigh and what your resting heart rate ought to be, and the wise doctor’s patriotic, good equipment cooperates to measure you correctly. (I have tried this myself without success. My scale is not a true patriot.) Mean, wicked scales that display unflattering numbers, and foolish, incompetent golf balls that do not traverse the correct distance, are promptly discarded and replaced with their more loyal counterparts. This is how value works! As Trump testified once in court, “My net worth fluctuates, and it goes up and down with the markets and with attitudes and with feelings, even my own feelings … Yes, even my own feelings, as to where the world is, where the world is...
