## Reproducibility: The Transparency and Openness Promotion Guidelines

In a previous post, we profiled the EQUATOR network and reporting guidelines. These guidelines stress transparency in reporting study methods, and most are relevant to study designs in clinical research, such as randomised controlled trials, epidemiological studies and systematic reviews. Taking a different vein, the Transparency and Openness Promotion (TOP) Guidelines were developed to enhance transparency in reporting of study

## Multiple linear regression in R

In a previous blog, we applied simple linear regression to an interesting problem: how well does a measure of wine density account for alcohol content. This was considered simple linear regression because we had one outcome variable (alcohol content) and one predictor variable (wine density). We can extend this approach to have more than one predictor. Specifically, we can use

## Statistics you are interested in: simple linear regression – part 1

We introduced simple linear regression in a previous series and learned how to perform it in R (1, 2). What is the theory behind simple linear regression? How is it used to understand relationships between variables? What is another way to perform it in Python? The hsb2.csv dataset (available here) contains demographic and academic test scores data from 200 students.
