Workshop: Advanced Regression Analysis in Natural Sciences with R Software

seminars, workshops |

Focusing on Poisson, Negative Binomial, and Zero-Inflated Regression, attendees will gain proficiency in modeling count data, handling over-dispersion, and addressing excess zeros. R packages such as glm.nb and ’pscl’ will be utilized for Poisson and Negative Binomial regression, while ’pscl’ and ’glmmTMB’ will facilitate Zero-Inflated Regression.

The workshop will extend its scope to include Cox Regression (and random effects), an essential survival analysis technique. Participants will explore ’survival’ and ’coxme’ packages in R, delving into time-to-event data and understanding covariate effects on survival outcomes. Through hands-on exercises and real-world examples, this workshop aims to equip attendees with a comprehensive skill set in advanced regression analysis, providing practical insights into modeling techniques for count data, survival analysis, and addressing issues related to excess zeros in the data.


The workshop will mainly consist of lectures and discussions, complemented by
hands-on practice with R codes. The structure will be as follows:

Day 1 (23 May, 9:15 am –12 noon)

1. Introduction to Linear Regression
2. Poisson Regression
3. Negative Binomial Regression
4. Zero-inflated Poisson and Negative Binomial Regression
5. R codes and real examples

Day 2 (May 24, 9:15am –12 noon)

1. Time to event and censored data analysis
2. Cox Regression
3. Mixed effects cox regression models
4. R codes and real life data analysis
