The agents represent a knowledge-diverse crowd, with each agent trained on a subset of available information. Now lets change the model a little bit (replace math using a technique that is likely unfamiliar to your audience, more description Logistic regression was used to analyze the relationship between [predictor variable 1], [predictor variable 2], [predictor variable, Before we report the results of the logistic regression model, we should first calculate the odds ratio for each predictor variable by using the formula e, We should also calculate the 95% confidence interval for the odds ratio of each predictor variable using the formula e, The Complete Guide: How to Report Odds Ratios. These two parts should be closely related. This description will include details about the assumptions that you made when running the power analysis, such as what effect size was assumed and a justification for that assumption.

Binomial Logistic Regression using SPSS Statistics Introduction. A binomial logistic regression (often referred to simply as logistic regression), predicts the probability that an observation falls into one of two categories of a dichotomous dependent variable based on one or more independent variables that can be either continuous or categorical.
