WSSPAS: An Interactive Web Application for Sample Size and Power Analysis with R Using Shiny

Öz:

Objective: The calculation of sample size and power analysis plays an importantrole in biomedical research. The most general definition of the calculation of the sample sizeand power analysis is to determine the minimum number of individuals that have the ability torepresent the population during the planning phase of the study. Since the statistical methodsfor each research plan are different, the calculation of sample size and power analysis will bedifferent. Therefore, it is difficult to calculate the sample size and power analysis manually foreach clinical trial. The aim of this research is to develop a new user-friendly web-based tool thatcalculates sample size and power analysis for hypothesis testing, diagnostic tests, correlation andregression analysis using the open source software R Shiny package and guides the researcherswith examples. Material and Method: This web tool will be updated upon the updated R softwarepackages, including shiny, shinydashboard, pwr, powerAnalysis, powerMediation, MKmiscand rhandsontable. Scripts were written for calculations that could not be done by these packages.Results: Hypothetical samples were created to introduce menus in the web-based softwaredeveloped for the calculation of sample size and power analysis, and screen images of the resultsof these samples were given. Conclusion: The designed interactive web application is freelyaccessible through http://biostatapps.inonu.edu.tr/WSSPAS. In the future studies, it is aimedto further strengthen the software by adding modules that can calculate sample size and poweranalysis for different multivariate statistical and machine learning methods.

WSSPAS: R Shiny Paketi Kullanılarak Örneklem Büyüklüğü ve Güç Analizi İçin İnteraktif Bir Web Uygulaması

Öz:

Amaç: Biyomedikal araştırmalarda örneklem büyüklüğü ve güç analizinin hesaplanması önemli bir rol oynamaktadır. Örneklem büyüklüğünün ve güç analizinin hesaplanmasının en genel tanımı, çalışmanın planlama aşaması sırasında popülasyonu temsil etme kapasitesine sahip olan asgari kişi sayısını belirlemektir. Her bir araştırma planı için istatistiksel yöntemler farklı olduğundan, örneklem büyüklüğü ve güç analizinin hesaplanması farklı olacaktır. Bu nedenle, her klinik deneme için örneklem büyüklüğü ve güç analizini manuel olarak hesaplamak zordur. Bu araştırmanın amacı, açık kaynak kodlu yazılım R Shiny paketini kullanarak hipotez testi, tanı testleri, korelasyon ve regresyon analizi için örneklem büyüklüğü ve güç analizini hesaplayan ve araştırmacılara örneklerle rehberlik eden yeni bir kullanıcı dostu web tabanlı araç geliştirmektir. Gereç ve Yöntemler: Bu web tabanlı yazılım, shiny, shinydashboard, pwr, powerAnalysis, powerMediation, MKmisc, WebPower and rhandsontable dahil olmak üzere güncellenmiş R yazılım paketleri üzerine geliştirilmiştir. Bu paketler tarafından yapılamayan hesaplamalar için komut dosyaları manuel olarak yazılmıştır. Bulgular: Örneklem büyüklüğü ve güç analizinin hesaplanması için geliştirilen web tabanlı yazılımda menüler tanıtmak için hipotetik örnekler oluşturulmuş ve bu örneklerin sonuçlarının ekran görüntüleri verilmiştir. Sonuç: Tasarlanan interaktif web uygulamasına http://biostatapps.inonu.edu.tr/WSSPAS aracılığıyla kolayca erişilebilir. Ayrıca ilerleyen çalışmalarda farklı çok değişkenli istatistiksel ve makine öğrenmesi yöntemleri için de örneklem büyüklüğü ve güç analizini hesaplayabilen modüllerin eklenmesiyle, yazılımın daha da güçlendirilmesi hedeflenmektedir.
