Hi everyone = i have been using =MODE() etc to impute missing values in column arrays.  Sick of this.  Seems unsophisticated, and not much fun, either. A more high level ML guy told me that he uses the Random Forest Classifier to rid himself of all the empty cells (which for me are all just in the form of tons of zeros).
2 QUESTIONS: First, what settings do I use to have the classifier leave the existing data undisturbed data undisturbed with the exception of the the zeros (which I want it to replace in some mysterious fashion far more inteligently than I can understand), and second

    i think the operator which does the trick for you is 'Impute Missing Values'.

    So Martin - the question I have is how much in the way of "contracting fees" would you charge to get me up and running on both Twitter and AWS?  i already have applied for and received both permissions etc...,  am eager to move forward if the costs are reasonable given that i am a former hedge fund manager (of significant size) and might well be able to provide you with a large amount of business going forward.  - - -Richard
