Once you have a fitted lmer model, whether it was fitted to real data or created from scratch, you can use that to simulate new data and assess the required sample size. The powerSim function allows us to estimate the power to detect a specific effect in the model. Here we are interested in the effect of the intervention.

sim: Run a Monte Carlo simulation with a structural equation model. This function can be used to generate data, analyze the generated data, and summarized into a result object where parameter estimates, standard errors, fit indices, and other characteristics of each replications are saved.

Finds associations between two human genomic datasets. To install this package, start R (version "4.4") and enter: install. packages ("BiocManager") BiocManager:: install ("SIM") For older versions of R, please refer to the appropriate Bioconductor release.

今年 (2020年) Google 发布了SimCLR，与Facebook AI团队 (FAIR)提出的MoCo都是近年 self-supervised learning 的重要里程碑。 Google Brain团队的SimCLR在ImageNet的分类问题上展示了SimCLR训练出的线性分类器达到了76.5％的top-1准确性，相对于以前的最新技术，相对改进了7％，与监督的 ResNet-50 的性能相匹配。 当仅对1％的标签进行微调时，我们可以达到85.8％的top-5精度，其标签数量减少了100倍，超过了AlexNet。 SimCLR这篇论文不仅仅是简单易懂的 …

2023年2月12日 · 这个代码是我从GITHUB上找到的，但是我有一行看不懂，这个代码是实现单一指数模型（single index model）的，fit=try（sim（）），sim（）我不知道是什么？ 题目来源及自己的思路

2024年6月27日 · sim simulates one (fx) or two (fx and fy) factor structures where both fx and fy respresent factor loadings of variables.

Structural Equation Models decompose correlation or correlation matrices into a measurement (factor) model and a structural (regression) model. sim.structural creates data sets with known measurement and structural properties. Population or sample correlation matrices with known properties are generated.

2016年4月11日 · To plot confidence bands I run a simulation using the sim () function from the arm package: The first one computes fine. The second one returns the following error: 'Sigma' is not positive definite. I actually am doing this with 8 different responses. Six of them worked fine and two of them returned this error. Does anyone know how to rectify this?

2022年4月1日 · $L$ and $R$ regard left and right, and $\sim_L$ left equivalence and $\sim_R$ right equivalence, but what is meant by $G/\sim_ L$ and $G/\sim_ R$? $G$ is some group and the equivalences are defined as below:
