<p>Hello,</p> <p>Which method do you use to assess the relative strength of each driver in a multivariate logistic regression ? This is very useful to show this on a pie chart to a non modeller audience.</p> <p>Kind regards,</p> <p>Toloc</p>

<p>@Toloc, One of the easy things to do after-the-fact might be to generate and visualize a straight correlation coefficient between the input variables and the output of the regression. Although its not perfect, it might be a good place to start and would give you at least a sense of which variables might be contributing to the final output of the model.</p>

<p>How about an odds ratio? or plot (table) the probability of Y=1 holding all other variables at their means - except the one you are showing, which you show the probability of Y=1 at meaningful values (maybe just the quartiles or 0/1 depending on the data type).</p>

<p>Why not use the standardized regression coefficients? These will assess the average change in the dependent variable for a one unit change in the given beta. This is an indicator of the impact of the dependent variable, holding all other variables constant.</p>
