Is there a fast method to remove those subjects with missing outcomes? Thanks for any help.

.... How is it possible to calculate the odds ratio for age (in this example) based on the spline? For example the odds ratio based on the spline between the age of, say, 20-30? Or even better: How can I plot the odds ratios against age in a continuous form? Many thanks for your help.

Hi to all I use a loop to plot 9 different histograms of 9 different transformations of one dataset (x). I want to label the histograms with the mathematical expression of each transformation (e.g. x^3). For that I've prepared a vector with the labeling names for "expression". > trans.expr <- c("x^3", "x^2", "x", "frac(1,x)",

Dear all I want to run a simple multiple linear regression model, say: mod <- lm(y~x1+x2+x3+x4) I have programmed a custom algorithm to calculate the p-values, because there is clustering present. I ordered the variables according to their p-value and want to stepwise eliminate the variables with the highest p-values. My question: How can I use "update" when I have only the
