question on Loss reserve testing - report year approach

For those who have read - "Loss Reserve Testing - a report year approach" by Fisher and Lange, can you show me how to calculate the "Average % increase in Claim cost (exponential)"( which is on table 4 of Page 196) ?

The similar problem on All 10 page 97 sample question 1.

It is said that "fit the data into exponential curve", but I had difficulty figuring it out.

Thanks.

best way to do that is to use the BA II Plus (I think there's another legal one that works too) to calculate the regression curve for you.

Take lns of the data points and fit a line. Then your fitted points are
exp(fitted linear points)
