The PM 2.5 checker written by R has been working nicely for me. I put a shortcut icon of this small script on my desktop PC, to check the air … Continue reading
The previous article introduced the sensitivity and elasticity to seasonal matrix model of imaginary annual plant. Both sensitivity and elasticity are partial derivatives. This means the values can only predict … Continue reading
The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. In this article, let’s try the sensitivity analysis of these matrices and the … Continue reading
The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. This article focuses on the meaning of the eigenvector at first, and then … Continue reading
Let’s challenge to build a matrix population model of annual organisms and then calculate the population growth rate λ using R. Consider a simple life cycle of imaginary annual plants; … Continue reading
