Jim:

I’ve been placing within the calculation for the t Stat for the bridge stats examine.  

The t stat operate entails gamma, the t stat operate makes use of the variety of levels of freedom,  however the Fortran gamma operate goes to infinity with n of 170, the t stat tables are all near the vary 0 to five , the tables checklist a dof of infinity, 170 just isn’t infinity it’s really fairly a small stats information set. 

 program Console9

 implicit none
 integer i
 actual*8 g, f

 ! Variables

 ! Physique of Console9
 print *, 'Good day World'
 f = 0.0
 do i = 1, 1000
 f = f+ 1.0
 g = gamma(f)
 write(*,*)i,f,g
 
 finish do
 

 finish program Console9

That is the consequence from this easy program.  

I used to be wanting on the EXCEL operate for t Stat of their information evaluation, they fairly comfortably say they’re calculating a t stat for a dof of a number of thousand of their linear regression fashions.  

I attempted becoming a curve by their t stat information, however one can’t match a easy curve, 

I used to be questioning, simply as a thought experiment, how these publishers of a t STAT desk can say they know infinity, infinity divided by infinity continues to be infinity.  And how on earth does EXCEL do a calculation I can’t do in Fortran, except they use an extrapolation operate. 

Anyway, sufficient complaining, fortunately I should not have to put in writing a gamma operate.
