PARAMETRIC ANALYSIS OF THE PRODUCTION PROCESS OF BACTERIAL NANOCELLULOSE MEMBRANES: EFFECT OF FERMENTATION AND BLEACHING TIME ON THE FILTRATION OF OILY WASTE

The codes developed in RStudio (version 4.4.0) were specifically designed to perform the statistical analysis of the study. The stats packages were used to perform the ANOVA and agricolae for the post hoc tests. In addition, functions were included to verify the assumptions of normality (Shapiro-Wilk test) and homogeneity of variances (Levene's test), considering a significance level of P &lt; 0.05. Comparisons between groups were performed using the Tukey HSD test本研究基于RStudio（版本4.4.0）开发了专用代码，专门用于执行本研究的统计分析工作。本次分析依托R基础统计包（stats）完成方差分析（ANOVA），并通过agricolae包执行事后检验。此外，代码中集成了验证分析前提假设的相关函数：用于验证正态性假设的夏皮罗-威尔克检验（Shapiro-Wilk test），以及用于验证方差齐性假设的莱文检验（Levene's test），所有检验的显著性水平均设定为P<0.05。组间比较环节则采用图基HSD检验（Tukey HSD test）完成。
