No weather reports here as I was on cultural duty. In New Orleans, due to their French heritage, French toast is known as pain perdu–"those French, they have a different word for everything "(S. Martin, 1977).
The cell phone only (CPO) and the cell phone mostly estimates, although large in magnitude, only tell us part of the story. We also need to know how different these members are in order for us to evaluate potential bias. Several papers had information that addressed this issue. A paper from some folks at the Pew Research Center found some differences between the cell phone only population compared to the standard RDD population. However, these differences disappeared with the application of demographic weights. Another Pew paper and study found more significant differences when looking at technology related issues. As will come as no surprise the cell phone only population had higher use of various technological products or services and had more positive attitudes about technology in general. These differences remain even after adjusting for demographics. A paper from Macro International found differences in regards to health items. Furthermore, some of these differences were small looking, small changes can have large implications in the public health area. With these three papers we see what is a common theme– there are sometimes differences between the CPO population and the RDD population depending on the topic at hand.
