(Twice) the Kullback-Leibler divergence between your model's density $f(\mathbf{x} ; \psi)$ and the true model $f(\mathbf{x} ; \theta)$ is

No, AIC does not necessarily assume that the residual distribution is normal. *However*, it *does* assume that the model was fit by maximum-likelihood rather than any other method (such as least-squares). If and only if the residuals of a least... |

For example: I'm having the string: `I want to see the overflowed words that are hidden in here`. And my div can only contain 3 words. So I want to see: `I want to +9`.

Okay, after the clarification I think I have a better handle on what you are trying to achieve. The code below almost exactly does what you want - but this is not an elegant solution, for sure. The fixed width, the character-limit still being there as a constant are both liabilities (e.g. whe... | You can create a variable that hold the length of the hole text minus the length of the text that can view in your case "I want to" is 9 chars then

and display `$scope.hiddenChars` value in case it is greater than zero |
