It provides the cpp function for FIM for the model ~1/(1 + exp(-b *(x - a)))^s, but when s is fixed (a two by two matrix).
FIM_power_logistic(x, w, param, s)Vector of design points.
Vector of design weight. Its length must be equal to the length of x and sum(w) = 1.
Vector of values for the model parameters c(a, b).
parameter s.
Fisher information matrix.
