Initial sample size guess for the Potvin methods [Two-Stage / GS Designs]
Hi ElMaestro,
I tried
Can you provide the function
My standard code gives:
How does it compare to yours?
I tried
GetStartNps.X3(GMR=0.95, CV=0.2, Pwr.T=0.8)
and was honored withError in Power.calc(nps1, GMR, CV, Is.St2 = 1) :
could not find function "Power.calc"
Can you provide the function
Power.calc()
, please?My standard code gives:
GMR : 0.95
target power : 0.8
‘best guess’ CV : 0.2
Fixed sample size: 20
power : 0.835
‘Type 1’ TSD, n1 : 16 (80.0% of N)
ASN : 20.0
power (interim): 0.619
power (final) : 0.851
How does it compare to yours?
