This is wonderful information, you hear most of this churned around major companies nowadays…..only problem is Egos’ in companies leadership is beyond help. They will not listen to the people below them even though they see the problems day after day. Anaylsis is done, just questions are of the wrong people, by the time they bring in the right people it is way to late. Most lower level employees keep their mouths shut for the fact of feeling under valued, being unheard/ignored, or simple fear. Usually the wrong people looking into the problems, if you own the problem sometimes you do not want to point out what you did incorrect. Seriously it comes back to ego.
Raster (Arithmetic) Overlay
Raster overlay superimposes at least two input raster layers to produce an output layer. Each cell in the output layer is calculated from the corresponding pixels in the input layers. To do this, the layers must line up perfectly; they must have the same pixel resolution and spatial extent. If they do not align, they can be adjusted to fit by the preprocessing functions discussed in Chapter 3. Once preprocessed, raster overlay is flexible, efficient, quick, and offers more overlay possibilities than vector overlay.
To close, let me underline that none of the above should suggest that marijuana won’t have an effect on the beer industry in the longer run, rather that I don’t see anything definitive one way or the other so far. Although I critiqued the Cowen and Company conclusion that marijuana has had an effect on beer sales in legalized states, I find their overall research agenda highly informative. Saying that there is no effect in the aggregate is very different than saying there is no effect in different portions of the market, and given widely ranging incidence rates by gender, ethnicity, income, and geography, marijuana has the potential to affect different segments of the beer market in quite different ways.
