Abstract

Survival Analysis encompasses fundamental statistical processes in data analysis where the main variable of interest is the time for the occurrence of a given event. Its great advantage is the possibility of analyzing the data set, even with the presence of incomplete times, called censored. The objective of this study was to analyze the effect caused by the insertion of percentages of censors into data of total life expectancy of male and female adults of a species of arthropod-pest, which may be an important agent in the country's animal production. Using the Logrank test to compare the survival curves generated, it was possible to observe that the randomly censored data at different levels of percentages would not affect the survival curve analysis of the individuals, since they were not statistically different.

引入随机审查对节肢动物布拉格生存时间分析的影响
生存分析包括数据分析中的基本统计过程,其中主要变量是给定事件发生的时间。它的最大优点是可以分析数据集,即使存在不完整的时间,称为审查。本研究的目的是分析在一种节肢动物害虫的雄性和雌性成虫的总预期寿命数据中插入审查者的百分比所造成的影响,该物种可能是该国动物生产的重要因素。使用Logrank检验来比较生成的生存曲线,可以观察到不同百分比水平的随机审查数据不会影响个体的生存曲线分析,因为它们没有统计学差异。
