Objectives To examine the accuracy of clinicians’ estimates of survival and to determine if any clinical profession is. The threestate Markov model described in which observed incidence is categorized according to policydefined thresholds gives the most reliable shortterm forecasts, whereas the dynamic linear model proposed, using logtransformed weekly incidence as the response variable, gives more reliable predictions of annual epidemics. Statistical researchers often use a linear relationship to predict the (average) numerical value of Y for a given value of X using a straight line (called the regression line).
