In this week's episode Patrick and Greg explore all the ways they lie about things when they teach, not the least of which is that there are actually no individual growth trajectories estimated in an individual trajectory growth model. They discuss why this is, how individual trajectory estimates can be obtained, and how these might be used in practice. Along the way they also mention the green light button, developmental milestones, love for semicolons, Jack Nicholson, baskets of data, Oprah, it's all crap, transparencies and dittos, yelling at your steering wheel, libertarians vs. socialists, carts and donkeys, catching squirrels, enemy on the field, being stung, bit, and chased, and persnickety models. Stay in contact with Quantitude!
