In particular, a negative binomial count regression model allowed us to find that fare evasion rates on buses increase as: (i) more people board (or alight) at a given bus door, (ii) more passengers board by a rear door, (iii) buses have higher occupancy levels (and more doors) and ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
Since the data consist basically of counts (“How many cues of kind x have been used?”), a linear regression model is not indicated. Poisson and negative binomial regression models are designed for count data. The former assumes that the conditional variances (the variances within the single ...

Multiple regression is very useful, but there are some assumptions that must be true in order for a multiple regression model to be accurate. In this lesson, learn about the common assumptions and pitfalls in multiple regression analysis. Related...
We used a negative binomial regression to account for the overdispersion of the dependent variable (retweet count). The predictors in the regression were dummy coded topic groups. Since we were interested in comparing topic groups representing a synergistic and an antagonistic climate, we chose the ...
GeneXproTools again creates model code for scoring and deployment that also supports data normalization. Below is an example in Python of a logistic regression model created using data standardized in the GeneXproTools environment. #--- # Logistic regression model generated by GeneXproTools 5.0 on ...
Concerning fractional polynomial regression: Existing commands fracpoly and mfp have a new syntax. They are now prefix commands, so you type fracpoly, ...: estimation_command and mfp, ...: estimation_command. Old syntax continues to be understood. Option adjust() used by fracpoly, mfp, ...
