Then, dividing .35 by 1.25 equals 0.28. Finally, multiplying 0.28 by 100 equals 28%, so the inflation rate for Joe’s cup of coffee between 2010 and 2024 was 28%.
WebMar 4, 2012 · As far as I know Lambda is an inflation factor related to the chi-square statistic. λ is computed by taking the median of the distribution of the chi-square statistic of the data, and dividing this median by the median of the corresponding (ideal) chi-square distribution. – user1236418 Mar 4, 2012 at 21:43 Add a comment 1 Answer Sorted by: 0 WebBriefly, a GWA study is an analysis of association between genetic markers and a disease or trait of interest.
