Re: [R] Survival model error

[R] Survival model error

Hi - Below is my code and then the error when I run the last line. time_np <- train1_na$tte event_np <- train1_na$censored X_np <- cbind( train1_na$AMT, train1_na$DISCOUNT_AMT, train1_na$high_price_pcnt, train1_na$EM_RECEIVED, train1_na$DM_RECEIVED, train1_na$TXN_WITH_RINGCODE,
