    Hi Sabya Sir, If I consider age group as continuous variable, model R^2 value is decreasing. However I am not getting coefficient NA values in this model. RACE is creating maximum probability (P value) error. Shall I remove RACE to improve better model further for Length of stay? Please suggest...

    In the assignment given for Day 2 for vector v1 <- c("Ravi","Shashi","Jaya","Reshma","Arun","Pulkit","Ravi"). Finding Ravi no. of times repeating finding is easy as we can count physically. Hence the coding given in answer sheet is probably right. However if the dataset is huge in vector v1 I...
