RLadyBug is an S4 package for the simulation, visualization and estimation of stochastic epidemic models in R. Maximum likelihood and Bayesian inference can be performed to estimate the parameters in a susceptible-exposed-infectious-recovered (SEIR) model, which is a stochastic model for describing a single outbreak of an infectious disease. The package is thus one step towards statistical software supporting parameter estimation, calculation of confidence intervals and hypothesis testing for transmission models.

RLadyBug是一个用于在R中对随机流行病模型进行模拟、可视化和估计的S4软件包。可以进行最大似然估计和贝叶斯推断，以估计易感-暴露-感染-康复（SEIR）模型中的参数，该模型是用于描述传染病单次爆发的随机模型。因此，该软件包朝着支持传播模型参数估计、置信区间计算和假设检验的统计软件迈出了一步。
