Some Statistical Analysis Tools

  • G*Power often used to determine the sample size (aka. number of participants) based on the statistical method/s will be used
  • Two tools I find very handy, i.e., jamovi and jasp for do the analysis without writing any additional line of code
  • Many researchers rely on the statistical software like IBM SPSS or R-Language
  • Other than those, the Python is the most powerful for data analysis. Python there are numerous libraries, e.g., NumPy, SciPy, Pandas are frequently used. Additionally, someone could check Python pingouin for statistical analysis. Someone can use pandas for data manipulation, SciPy or statsmodels for tests, and matplotlib or seaborn for plotting results. Moreover, If someone wants to work on eye-tracking data analysis, the package, pymovements is very handy.

Variance, Noise, and Artifacts in Real-Time Path Tracing

less than 1 minute read

Published:

(work in progress…) Noise is also referred as error, visual artifacts. In ray tracing-based rendering, it is referred to as variance. High variance represents more noise as the number of samples has not converged enough to the actual right result of the integral (Light Transport Equation).

02: Perceptually Aurora is less vivid than Camera

Rod cells are more sensitive than cone cells and are almost entirely responsible for night vision. However, rods have little role in color vision, which is the main reason why colors are much less apparent in dim light.

GitHub Pages

  • GitHub allows only one free hosting static page against per github account
  • Developers can develop their page with HTML, CSS, Javascript, or any other languages if like.
  • Important: for this your github account name, and newly created repository name must me the same. For example, if your github account is sample-git, then your page name must be sample-git.github.io, which later will generate url https://sample-git.github.io
  • You can not push files to your repository, upload templates, or develop manually.
  • There are many awesome repositories for templates, for instance, jekyllthemes.
