This is a simulated dataset following the study design of the [http://www.ncbi.nlm.nih.gov/pubmed/12653820Health Evaluation and Linkage to Primary (HELP) Care study]. These data are not real but simulated and intended for demonstration of various multivariate statistical, computational, analytical and visualization protocols for data interrogation.

==Background==
 
−
The original Health Evaluation and Linkage to Primary (HELP) Care study had recruited adult inpatients in a detoxification unit. Researchers randomized the patients with no primary care physician to receive evaluations and a brief care intervention and investigated their findings relative to prior enrollment in primary medical care. The complete original dataset can be found [http://www.math.smith.edu/sasr/datasets.php here].

−
Data for continuous variables reports observed range at baseline.
 
−
* * marked variables are recorded at baseline and follow up (e.g., mcs is baseline measure, mcs1 is measure at 6 months, and mcs4 is measure at 24 months);
 
−
* for each of the 20 items in HELP section F1 (f1a, …, f1t), respondents were asked to indicate how often they behaved this way during the past week (0=rarely or none of the time, less than one day; 1 = some or a little of the time, 1 or 2 days; 2 = occasionally or a moderate amount of time, 3 or 4 days; or 3=most or all of the time, 5 to 7 days);
 
−
* Reverse coding was used for items f1d, f1h, f1l, and f1p (as these questions are intrinsically positive in nature (e.g., hope), where as the remaining once are negative in nature (e.g., blues)).
 
−
* Some subjects (e.g., case 13) did not have metadata (e.g., e2b) recorded for them.
 
−
* "." (period) denotes missing or incomplete observation.

SOCR Simulated HELP Data - SOCR Activity: Simulated Health Evaluation and Linkage to Primary (HELP) Care Dataset

SOCR Simulated HELP Data

See the SOCR Simulated HELP Data first. These data can be copy-pasted using the mouse from the HTML table into a plain text file "help_data.csv".

Classroom use of this data set

The simulated HELP data can be used to demonstrate a number of different statistical, modeling, inferential and data analytic techniques, see list below. The following SOCR HELP Activity demonstrates exemplary use of these data using R.
