As global warming is becoming an issue for extreme weather, cooling technology has been faced with new challenge, including a requirement of efficiency and effectiveness. It was not until 1960s did passive radiative cooling technology gain the attention from researchers, such technology had stopped for decades. This article will offer some traditional passive radiative cooling solutions.
Here are some results of weighted sample linear regression which is called Robust Standard Error. Through multiplying weight to each sample, and eliminating outliers, it has showed a great enhancement in residual diagnosis.
