This note presents an overview of the assumptions for both tests which must be satisfied to ensure the tests are appropriate, discusses the usefulness of using Pearson's Chi-Square test as a preliminary test before using binary logistic regression, and presents an overview of how to...
When you performbinary logistic regressionusing the logit transformation, you can obtain ORs forcontinuous variables. Those odds ratio formulas and calculations are more complex and go beyond the scope of this post. However, I will show you how to interpret odds ratios for continuous variables. Unl...

11 LOGISTIC REGRESSION - INTERPRETING PARAMETERS 11 Logistic Regression - Interpreting Parameters Let us expand on the material in the last section, trying to make sure we understand the logistic regression model and can interpret Stata output. Consider first the case of a single binary predictor,...

This function produces a bunch of scalar measures of fit for binary models. If you are unfamiliar with some of these, see Long (1997) or Long and Freese (2005) for a discussion. You can also use the pre function to find the proportional reduction in error and the expected proportional ...
The full data set used in our analysis (13 tissues, including 4 replicated tissues) consisted of the binary accessibility values for 81,173 cells and 436,206 peaks (1.2% overall rate of accessibility). Note that all peaks had fragments mapping to at least 40 cells, so no extra step was ...
