Can someone please guide me with the correct syntax to calculate
weight/height z -scores including the -1.5sd

A better option may be to get access to a z-score table with a -1.5sd
column

Also please advise how I can handle calculations that fall out of range of
the table values eg. A child whose z-score is 2, if my table only has
values for -3sd, -2sd, -1sd and 0.

I don’t want it forcibly allocate a z-score within this range just because
the table does have a column that has the actual result.

Is it possible to generate an out of range exception or something like
that??

Are you following a particular implementation document to complete this
calculation?

Generally speaking, all z-score calculations are approximations between
two points, using a best fit, so it would be difficult to produce an out of
range value for a value that fit in between two other elements.

But Is there a way i can at least calculate the -1.5 zscore??

Which Z-Score table are you using for your data? It should theoretically be
possible to add new calculations to the table for new ranges.

Thank you Clayton…

I can skip the out of range part…

But Is there a way i can at least calculate the -1.5 zscore??
