Banerji et al. (A-3) followed non–insulin-dependent diabetes mellitus (NIDDM) patients from onset of their original hyperglycemia and the inception of their near–normoglycemic remission following treatment. Subjects were black men and women with a mean age of 45.4 years and a standard deviation of 10.4. The following table shows the relapse/remission experience of 62 subjects.

Calculate the survival function using the Kaplan–Meier procedure and plot the survival curve.
