• RE: Breakdown of types of computers in household by state AND Age Demographic

    Note that if you want to have appropriate standard errors, you need to invoke `library(survey)` or `library(srvyr)` and use replicate weights.

  • RE: Ratio of Income to Poverty by County and Race

    Dear Derek,

    The only way I've been able to do this is build a model with age - sex - race -poverty level (above/below/undefined) and poverty200 (above/below 200 FPL)  at the PUMA level (large area) using pums data for a PUMA containing the small area…

  • Different coefficients of variation with same information

    Hi, all. We often use coefficients of variation (CV = standard error ÷ estimate) as a rough guideline for statistical reliability: CV < 0.15 is pretty trustworthy; CV > 0.30 is not to be trusted. But the CV value depends on how the estimate is expressed…

  • Comparison of RACE and Hispanic STATUS for National Tables 2019 to 2021

    Someone noticed that I had incorrectly computed (using Excel) t in the First Panel of the Table, where I report percent  Total Race for the 2019 ACS.  The table below reports corrected percents and corrected percent differences for that table.  I should…
