Last week I said I was going to change the scope of my project: I was going to build a “CT Coffee Index”. The intention behind this change, is that if I can find supporting information of potential economic development of census tracts based on the behavior of the coffee shops, I could later extend … More CT Coffee Index – Differences among groups
I was working on finding a meaningful metric to explain alcohol access in neighborhoods. One of the assumptions I made was that different types of alcohol outlets have different implications in social characteristics and economic strength of a neighborhood. I am curious to find out whether this assumption is supported by statistics. Prepare the Dataset … More Comparing Groups: Liquor License Types and Social Fabric
Valid days for Local Business? According to my calculation I did before, the average day of business license in Boston was 1.6-year, which is 545 days. Based on this estimated value, I conducted the T-test in order to see there is difference between mean of local business license validation and the estimated value. One Sample … More Comparing Groups
According to my exploratory plot on Week 6, it seems that median income and sex ratio has some kind of correlation with the number of liquor licenses per.k metric. I do expect rich neighborhoods to have more alcohol outlets, especially the on-premise ones we are looking at. Because these areas normally have more thriving business … More Correlations and Regressions: Who has the most privileged access to alcohol outlets?
Let’s recall the objective of my project: I’m trying to explain the behavior of business licenses over a period of time from 2007 to 2015 and identify if is there any kind of “pioneers” businesses that might indicate that a census tract is going to be gentrify. So, in order to get that information, I’ve … More What explains Business Licenses in a Census Tract?
Intro So far, I have been focusing on local business in Boston. This is interesting because it could reveal some clues about local economy. For example, if a certain area has lots of local business than other areas have, it might be reasonable guess that the area would have higher level of local investment coming … More Correlation and Regression: # of local business & local investment
For this assignment I first explain a few improvement I made for my latent variables since last week: Last week I created different data set based on the amount of licenses that were issued each year. The good thing about that was that we could measure how many NEW licenses were issued, but the picture … More Mapping Business Licenses
Previously we discovered that the Central district has much higher number of liquor licenses per capita. This is no surprise since normally the city center has much more thriving businesses but less residential properties (hence a smaller population density). Using the tax accessor’s data, we can see directly from the map how much this difference … More Mapping the City: On-Premise Liquor Access and the Thriving of Businesses
To begin with, my latent construct model I suggested last week was as follows. The reason why this construct is interesting is that I could figure out the local business level in each district. The number of business only tells about how many business exists, but exploring the local businesses allows me to know how … More Linking Data: Local Business in Boston
There are two directions to further the analysis of alcohol consumption: the relationship between alcohol licensing and econoimc growth, and the impact of alcohol consumption in the context of public health. Because of the lack of data on off-premise liquor licenses, it is impossible to estimate how much alcohol people consume at home, thus the … More Linking Data: Census Indicators and Alcohol Consumption
