I did want to post a few basic questions:<br /><br />Firstly, I notice that some PatientID's have only a single RecordID; my understanding is that a minimum of 2 were required and am suspicious that random partition into training and test sets was conducted at the RecordID, rather than PatientID level.<br /><br /><br />Secondly, I see an interest in predicting length of stay for specific outcomes from past visits (excluding the terminal visit altogether). What is your opinion of this?Anonymoushttps://www.blogger.com/profile/13535826812176004611noreply@blogger.com
