Success probability and derivatives of the
negative log-likelihood of a logistic model
Usage
rho_prime_logistic(x)
f_prime1_logistic(x)
f_prime0_logistic(x)
Arguments
- x
Numeric. Input variable.
Details
rho_prime_logistic
computes the successs probability of
a logistic model \(\rho'(t) = 1/(1+e^{-t})\).
f_prime1_logistic
and f_prime0_logistic
are
the derivative of the negative log-likelihood when \(Y=1\) and \(Y=-1\).
