Relational model life tables: an example (cont.)

Step 3

Once we have alpha and beta we use these to adjust the standard logits according to the formula:

Adjusted logits = standard logits * beta + alpha

And then antilogit these values to return to the l_x scale. The antilogit formula is:

l_x = 1/(1+ exponent(fitted logit * 2))

which is easily executed by spreadsheet.

These are our fitted life table (l_x) values!

The complete table, with fitted values, is shown below.

See Appendix 1 for more details about the fitting procedure.
