good day
previously I asked about how to do a nomogram in R after importing the files from SPSS.
my study is about factors predicting free flap thickness. in SPSS I already did a linear regression to check the factors that affects thickness
( outcome is flap thickness" continuous" and predictors " age>50, gender, BMI>23 " binary" ).
and I tried to follow this site ( rms Package (hbiostat.org)
however, I can not generate anything since my x variables were not continuous
again, I'm not familiar with statistics, please help TT
