Greetings,

I'm performing research that will help determine the size of observed space and the time elapsed since the big bang. Hopefully you can help!

我正在進行的研究將有助於確定觀察到的空間的大小以及自大爆炸以來所經過的時間。希望你能幫忙!

I have bilinear data on which I want to perform two linear regressions. There is a point at which the slope and intercept change, and I need to (write a program to) find this point.

我有雙線性數據,我想要進行兩次線性回歸。斜率和截距有一點變化,我需要(寫一個程序)找到這一點。

Thoughts?

There was a paper on this a few years ago by Joo and Qiu at Minnesota: http://pubs.amstat.org/doi/pdf/10.1198/tech.2009.07163
