Webx <- c(x1,x2) y <- c(y1,y2) The first 100 elements in x is x1 and the next 100 elements is x2, similarly for y. To label the two group, we create a factor vector group of length 200, with the first 100 elements labeled “1” and the second 100 elements labeled “2”. There are at least two ways to create the group variable.

WebJul 8, 2024 · I have a binary variable (biological sex) and I am concerned about the sign (positive or negative) of the estimate in my linear regression. In my data.frame, female is coded as 2 and male is coded as 1. I'm considering recoding it so that female is coded as 0 and male is coded as 1.
WebIn logistic regression binary variables may be standardise for combining them with continuos vars when you want to give to all of them a non informative prior such as N~ (0,5) or Cauchy~ (0,5). The standardisation is adviced to be as follows: Take the total count and give. 1 = proportion of 1's. 0 = 1 - proportion of 1's.

Generally the probability of the two alternatives is modeled, instead of simply outputting a single value, as in linear regression.
