I'm using Ipfraking to generate weights for my survey data.

For some reason when the iteration finishes and the Summary of the weight changes table comes up, it only wrotes invalid %format, nothing else. The same code works on other datasets.

The code:

svyset RecordNo, vce(linearized) singleunit(missing)

gen byte initial=1

matrix size=(84.0, 9.0, 6.0, 1.0)
matrix colnames size= 1 2 3 4
matrix coleq size = initial
matrix rownames meret = size

matrix sector=(4.24, 7.17, 9.34, 17.63, 61.62)
matrix colnames sector = 1 2 3 4 5
matrix coleq sector = initial
matrix rownames sector = sector

ipfraking [pw=initial], ctotal(size sector) generate(rakedwgt1) nograph
