I have just fitted my data to a sum of Gaussians, and recieved NaNs as the confidence bounds of some of the coefficients. What does this mean? There must be meaningful numbers as confidence bounds, however far apart they may be. How can they be NaNs?

NaN is the result of a 0/0 or Inf/Inf or other such operation.
Maybe you’re fitting too many Gaussians?
