Notes: The row of “reference probabilities” reflects all dichotomous variables set at 0 (i.e., the reference categories) and organizational size set at its mean. Each subsequent row reflects probabilities calculated for that particular independent variable with all other dichotomous variables set at 0 and organizational size set at its mean, unless otherwise noted. Reported predicted probabilities are for illustrative purposes and do not account for standard errors of the estimates. Some rows, when summed, are greater than one due to rounding.
