The Estimation of (Covid-19) Cases in Kurdistan Region Using Nelson Aalen Estimator

It is described how the Nelson–Aalen estimator may be used to control rate of a nonparametric estimate cumulative hazard function based on right censored as well left condensed survival data, furthermore can utilized various amounts. This technique mostly applied data and product quality similar incorporated relative mortality in multiplicative model with outer rates infection straightforward epidemic model. shown that tallying measures produce structure permits brought together treatment all these different conditions, main little massive sample properties assessor are summarized. weighted average Nelson-Aalen reliability estimates over two time periods. The suggested estimator's suitability utility selection reviewed. And real-world dataset evaluated demonstrate proposed utility. work proposes simple nearly unbiased fill this gap. information was gathered from Ministry Health's website between October 1, 2020, February 28, 2021. results Nelson Allen Estimator demonstrated odds surviving were higher during short period after being exposed virus. As passes, possibilities become slimmer. closer comes value 1 0.5 upward, greater chances infection.
