+ | **MLS Discussion 6/ | ||
+ | |||
+ | 1) summarized participant recruitment, | ||
+ | schedule, and sample descriptives. | ||
+ | |||
+ | 2) summarized potential variables of interest: variable labels, computation to create composites if available, variable coding | ||
+ | |||
+ | 3) data visualization: | ||
+ | |||
+ | 4) discussed issues with missing data, mismatched coding in documentation and data, missing variables of interest | ||
+ | |||
+ | Future plans | ||
+ | |||
+ | 1) fully examine documentation including MLS data orientation, | ||
+ | |||
+ | 2) acquire additional data to include more variables of interest | ||
+ | |||
+ | 3) try to identify why some data is missing- skip outs or missing in T wave years? | ||
+ | |||
+ | 4) find data on birth year and recruitment group | ||
+ | |||
+ | 5) separate phenotypes by gender | ||
+ | |||
+ | 6) confirm rescoring structure for variables that do not match codebook | ||
