HOW TO INTERPRET COEFFICIENTS IN A POISSON REGRESSION?
Q2: In that case, in a poisson regression, are the exponentiated coefficients also referred to as "odds ratios"? – oort A2: No. If it were logistic regression they would be but in Poisson … From stats.stackexchange.com
POISSON OR QUASI POISSON IN A REGRESSION WITH COUNT DATA AND ...
So now, I'm trying a regression with Poisson Errors. With a model with all significant variables, I get: Null deviance: 12593.2 on 53 degrees of freedom Residual deviance: 1161.3 on 37 … From stats.stackexchange.com
WHAT ADVANTAGES DOES POISSON REGRESSION HAVE OVER LINEAR …
The Poisson regression then relates this parameter to the explanatory variables, rather than the count. The reason this is better than normal linear regression is to do with the errors. If our … From stats.stackexchange.com

DIFFERENCE BETWEEN POISSON AND BINOMIAL DISTRIBUTIONS.
The poisson distribution counts discrete occurrences among a continuous domain. Ideally speaking, the poisson should only be used when success could occur at any point in a … From math.stackexchange.com
Oct 4, 2013 Poisson distributed data is intrinsically integer-valued, which makes sense for count data. Ordinary Least Squares (OLS, which you call "linear regression") assumes that true … From stats.stackexchange.com
POISSON REGRESSION TO ESTIMATE RELATIVE RISK FOR BINARY OUTCOMES
The same cannot be said of relative risk or Poisson models. A poisson model is useful too when individuals may have an "outcome" more than once, and you might be interested in cumulative … From stats.stackexchange.com
