coldfission Posted October 3, 2008 Share Posted October 3, 2008 I need to write a program that will take our inventory and find out the predicted date when we will reach quantity = 0 The only way i have decided to do this is to take our "Inventory Changes" (date and quantity at that time) and make a graph of it. Then, find the best fit line (quadratic would be nice but linear works) of that graph. Then, i can find when that best fit line reaches zero and find out what the date is at that point. That will be our predicted quantity = 0 date. Are there any tools already made for php that will find a best fit line? Is there another way to predict this without finding the best fit line?
