查询词典 parametric curve

Especially,when there are local changes among the data,and a single parametric distribution family can\'t describe the observed data accurately,finite mixing distribution models usually make excellent performance.

特别是，当观测数据有局部变化，而单一的参数分布族无法确切地描述观测数据时，有限混合分布模型表现出色。

The constituent ratio, prevalence and average ectoparasite abundance were used to reflect the prevalence and density of ectoparasites. Non-parametric Mann-Whitney U-tests were used to test differences in the abundance and richness of ectoparasites between female and male hosts. Spearman correlation analysis was used to analyze the relationship between ectoparasites and the body parameters of hosts.
