Hi,
last year the non-linear Wald-Test was implemented. The following
example is given:
<script>
function restr (matrix *b)
matrix ret = b[1]/b[2] - b[4]/b[5]
return matrix ret
end function
open data4-10
ols 1 0 2 3 4 5
restrict
rfunc = restr
end restrict
</script>
But running this script yields the error:
----------------------
? restrict
? rfunc = restr
? end restrict
Data types not conformable for operation
Error executing script: halting
> end restrict
----------------------
I am not sure what the exact problem is.
According to the Gret reference manual (gretl 1.9.1,page 47) the function restr should be
declared as
function restr (const matrix b)
