Dear R forum
I have following variables -
EAD = 1
LGD = 0.45
PD = 0.47
M = 3
# Equation 1
R = 0.12*(1-exp(-50*PD))/(1-exp(-50)) + 0.24*(1-(1-exp(-50*PD))/(1-exp(-50)))
b = (0.11852 - 0.05478 * log(PD))^2
K = (LGD * pnorm((1 - R)^(-0.5) * qnorm(PD) + (R / (1 - R))^0.5 * qnorm(0.999))

Hi
Reading the error message carefully you can see that f() is not defined at 0:
uniroot(f, c(0, 1))
Error in uniroot(f, c(0, 1)) : f.lower = f(lower) is NA
f(0)
[1] NaN
If you plot f() in the interval (0,1) then you'll see there is two solutions:
uniroot(f, c(0.0001, 1))
Error in
Dear Sir,
Thanks a lot for your wonderful guidance. It gave me a new vision to look at
teh equations. Really appreciate.
Thanks a lot once again.
