weib2dprb

PURPOSE ^

returns the probability for rectangular regions.

SYNOPSIS ^

[y ,eps1] = weib2dprb(phat,x1lo,x1up,x2lo,x2up)

DESCRIPTION ^

 WEIB2DPRB returns the probability for rectangular regions.
 
  CALL: [P tol] = weib2dprb(phat,x1lo,x1up,x2lo,x2up);
 
    P    = probability
    tol  = absolute tolerance, i.e., abs(int-intold)
    phat = parameter vectr (see weib2dfit)
    xilo = lower integration limits
    xiup = upper integration limits
  
   The size of P is the common size of XILO and XIUP.  
  
  Example
   x1=linspace(0,10)';
   phat = [ 1 2 .5 1.5 .8];
   weib2dprb(phat,1,2,1,2)
   f = weib2dpdf2(x1,x1,phat);
   pdfplot(f); hold on,
   plot([ 1 1 2 2 1],[1 2 2 1 1]), hold off
