What if I need subgroup identifiers with repeating groups of a certain size?

A spreadsheet formula can generate a repeating identifier variable of a certain size. For example, the formula: =v0-n*trunc((v0-1)/n) where n is the maximum group size, can be used to generate a variable with codes up to that size. For example, when n=4, then the following values (codes) of the grouping variable will be generated: 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4,... When I use the Case Weights option, I do not believe the results are correct.

Case Weights must be integers. If the variable chosen as the weighting variable is a non-integer number it will be truncated to become an integer. The Case Weights option treats values of a selected variable as integer case multipliers when processing the data.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
