Hi, robmio

Your screenshot was the one I get, without LOCAL s,z;

I did a emulator reset, to be sure: build 2.1.14181 (2018 10 16)
Then, load back quad and SRP_qkv ... Everything is working fine.

After running SRP_qkv(4.511, 8, 12) again. These are in Cas variables:

SRP_qkv (Function) 2KB
quad (Function) 0.25KB
quad6 (Function) 9KB

Paradoxically, with hard reset, LOCAL s,z; is not needed anymore.

Code:

#cas // Studentized P_Value, from q,k,v
SRP_qkv(q,k,v) :=
1 - √(2/π)*k*(v/2)^(v/2)/Gamma(v/2)
* quad(s -> s^(v-1)*exp(-v*s*s/2) * 
  quad(z -> exp(-z*z/2) * normald_cdf(z,z+q*s)^(k-1)
, -inf, inf) (1)
, 0, inf) (1)
#end
