This assumption can be tested empirically by plotting the observations on a normal probability graph. and reports the results of several statistical tests. This process continues until there is a predicted outcome for each observation in the sample.) For example. Investigators who have research designs that involve nested subjects should consult a biostatistician for assistance. and exp indicates that the base of the natural logarithm (2. and Z be a dummy variable. a study to examine the effect of different factors on complication rates following total knee arthroplasty was undertaken in a province of Canada (Kreder et al. interest focused on comparing the regression lines predicting insulin activity from body mass index (BMI) in women who had normal versus elevated thyroid levels. the antilog).
