One of my classmates (Alissa) has been using a measure that shows whether the owner of a property is a resident of Revere. This is the code that she contributed to make this measure for our group midterm. RevereTA <- read.csv(“valuation.csv”) RevereTA$Revere <- ifelse(RevereTA$OWN_CITY == “REVERE” | RevereTA$OWN_CITY == “Revere”, 1, 0) RevereTA$NotRevere <- ifelse(RevereTA$OWN_CITY … More Anova and T-Test for Work Value in Revere

I then utilized these new “ecometrics” as a way to evaluate the effect that a voting precinct has on a parcel’s land value.

In particular, I will try to see if the significance between buildings owned … More Comparing Building Types and Owner vs. Non-Owner Occupied Buildings in Arlington

The first part of this post creates a category for zoning, looking at how each parcel in Newton is zoned. The second part of this creates my manifest variable for landscape … More Newton Landscape Altering Permit Comparisons

The government is incentivizing business to move to this area in order to create more of a city center feel in the community. Watching developments on … More T-Test and ANOVA Tests: Chelsea
