Case shiller on zip code basis

[drunkle]

esmith:

can you add graphs that chart the rate of change of the particular areas?

any specific areas you want?

also, (maybe you did this already? or case-shiller did?) apply filters that weed out 95, 90, and 75 percentile data?

What do you mean?

no preference for area, figure you could easily do it for all your existing classifications…

filter out the 5th/95th percentile data, 10th/90th, 25th/75th… as in, get rid of the data that is outside of the percent range in the distribution…

i don’t recall the exact method of doing so and i dont even recall the proper term. but essentially, lop off the top and bottom set of data that is less than the bottom 5% and greater than the top 95% of the data in the distribution. so for example:

dataset:
15
15
15
45
45
55
65
65
75
95

median = 50, 10% percentile = 17, 90% = 93. eliminate values that fall outside of the percentile range and then recalculate median and plot. for this dataset, median becomes 60…

i’m wondering if doing such would get rid of aberrant values (prices) and affect the median, showing a more accurate picture… or maybe doing such would really only be useful with calculating mean… or maybe it’s just a waste of time as the values dont change much…

December numbers are in!

[img_assist|nid=6169|title=San Diego average – 07/12|desc=|link=node|align=left|width=466|height=354]

In the last three months, we’ve reversed the appreciation of February, March, and April of 2004.

C-S predictions:
November: 209 (-16.5%)
December: 202 (-19.5%)
January: 194 (-22.5%)

At this rate of decline, sometime in 2010 house prices will hit zero.

esmith. Great data. I hope my posts bore you enough to add Rancho Santa Fe (92067) and Santa Luz (92127) to your analysis.

Esmith, this is great data. I also really appreciate your earlier graph showing the overlay between your implementation and the official case-shiller data. I’m a scientist, so I appreciate a nice graph, and confirmatory comparisons. This is really helpful!

Now, if your yellow line would just keep dropping….
