Add EGFR data
Break down residual calulation into steps to help debugging
Fix adding new data
Bugfix: substitute (NCases, NIhp) numerical constantw with variable names
Example for removing end of the chain

Needed when interactive PyMC is paused before coda export.
As first step look how much burn-in to discard, then look again
Indent and doc code block # Display highest "lag 5" autocorrelation
Update vars to exclude in block # Display highest cross correlations +

- Update variable list to exclude
- Insert remark for future updates
- Indent and doc code block
Use all Ihp variables and Group, use better scatterplot method

- Indent and doc code block # Latent x result with Ihp variables:
scatterplot and correlation matrix
- Rename 'x saved into d' as x1
- Extract all Ihp variables, not only given ones
- Extract Group variable, too
- Use PerformanceAnalytics / chart.Correlation for scatterplot
Burn-in of 10 is enough here
Run results

- Posterior SDs equal to priors.
