1. ### Iterated Function Sequences Accumulation: Help!

Homework Statement We are given three contractions which generate the Sierpinski right triangle: A0 = \frac{1}{2} <x , y> A1 = \frac{1}{2} <x-1 , y> + <1 , 0> A2 = \frac{1}{2} <x , y-1> + <0 , 1> We are asked to find the points on which the sequence (A2\circA1)n(<x0 , y0>) ) --...
2. ### Iterated Function Sequences Accumulation: Help!

Not quite sure how to approach this problem at all. We are given three contractions which generate the Sierpinski right triangle: A0 = \frac{1}{2} <x , y> A1 = \frac{1}{2} <x-1 , y> + <1 , 0> A2 = \frac{1}{2} <x , y-1> + <0 , 1> We are asked to find the point to which the sequence...
3. ### Econometrics: Controls and Difference-in-Differences

Sorry for the double post with the SS section -- I thought this was probably a better place to ask this question. Hello all, I'm working on an econometrics project in which I'm using difference-in-differences approach to estimate the effects of the 1996 TANF welfare reform in the US. My main...
