PROGRAMMING: R Codes

  • Misclassifying Odds Ratio

    Functions for dealing with misclassification of ORs due to imperfect sensitivity and specificity, the first code, episensi.R, is similar to the episensi function in STATA that adjusts/corrects biased ORs when we assume certain sensitivity and specificity. The second code, misclassOR.R, does the "opposite" whereby it determines what the biased OR would be if the sensitivity and specificity were imperfect. 

 

  • Frequency Polygon

    freqpoly.R is an algorithm to implement a graphical device for understanding the shapes of distributions that are similar to histograms. Frequency polygons are also a good choice for displaying cumulative frequency distributions.

 

  • Automated change-in-estimate

    The function dropCIE.R was developed to use with the glm function in R and the logit link function to help select a "final" model via CIE of the odds ratio (OR) for some set tolerance using an all-possible-models manual backwards selection procedure. It is analogous to the drop1 or step functions in R. For more detail please see the affiliated post.
