Discussion on statistical methods in the human efficacy evaluation of cosmetics
The study aimed to explore the statistical analysis method of repeated measurement data in the human efficacy evaluation of cosmetics.Based on the algorithm and principle,taking the evaluation of whitening effect of cosmetics as an example,statistical analysis and data interpretation are realized by SPSS.Repeated measurement ANOVA and generalized estimation equation can be used to compare the processing factors and time factors of measurement data at different levels,and the interactive effects can also be analyzed.The statistical results are basically consistent.The generalized estimation equation can be used to analyze the hierarchical data.Repeated measurement ANOVA and generalized estimated variance may have a good prospect for the study of human efficacy evaluation of cosmetics.
