Multivariate Analysis to Will Die When
Mohammed Alharbi Hap 464
The objective of the workAnalysis to Predict Who Will Die When.HOW ? Create Training and Validation set . Use the training set to calculate likelihood ratio. It’s important because it gives forecast information regarding
health outcomes. this assignment teach us to explore data and locate exact
information among big data.
Data sourceNumber of cases
What is the distribution of the data
• Data source from the Assignment Select count (*) from dbo.final • The total number of cases( 17,443,442 number of cases)• distribution of the dataThe average is -59.5318And the Standard deviation- 4.2931
Average AgeAtDx: 59.53186Standard Deviation of
AgeAtDx: 4.293136
Start Dataset (hap464.dbo.final): 17,443,442 Cases and 829,827 IDsHas visit after death Removed: 17,432,694 Cases and 829,659 IDs>365 Dx/Yr Removed: 17,379,218 Cases and 829,603 IDs This is your clean data.80% Training Set From Clean Data: 13,760,416 Cases and 657,905 IDs20% Validation Set From Clean Data: 3,619,297 Cases and 171,698 IDs
Preparation of the data
17,443,442
10,748 diagnoses removed
53,476 diagnoses removed
829,827 distinct IDs
Remove Zombies:
168 distinct IDs
Calculating Likelihood Ratios
(The number of patient who will died within 6 months /Dead Patients)
(The number of patient who will died within 6 months/ Alive Patients)

Calculate sensitivity and specificity of the predictions
Posterior Odds
Alive Dead
True Condition
Alive True Positive False Negative
Dead False Positive True Negative
Usefulness of the project • The usefulness of the project is to practice doing SQL in a large data set by using the skills of
codes, Also to figure out Selecting appropriate method of data analysis and removal of confounding in the data, Visually present complex multivariate data and Interpret quantitative findings and relate it to specific policy issues or management decisions.
• In fact, It’s important in our future work filed
