What are identifiability conditions?

What are identifiability conditions? They're like clues that help us tell different things apart when we’re solving a puzzle.

Imagine you have a bag full of colorful marbles, red, blue, and green. You can't see inside the bag, but you can take out some marbles and count them. Now, if I tell you how many red and blue marbles were taken out, but not the green ones, it might be hard to know exactly how many of each color was in the bag.

That’s where identifiability conditions come in, they’re like extra clues that help us figure out what’s really going on. For example, if I also tell you how many marbles were taken out total, or maybe some special rule about how red and blue marbles behave together, then you can use those clues to know for sure how many of each color was in the bag.

Think of identifiability conditions like clues that help detectives solve mysteries. Without enough clues, there might be several possible answers, but with the right ones, they can find the real answer. So instead of guessing, we can know for sure what’s going on inside our marble bag!
