Phenotype Regression Configuration ================================== A phenotype regression configuration file is used when generating the phenotype browser's database files for a given study or dataset. It determines which measures to construct regressions against. The format follows the general INI style. Regression configurations can be created as a separate file or embedded in a phenotype database's own configuration file for ease of access. Example Configuration --------------------- .. code-block:: ini [regression.age] instrument_name = common measure_name = age_at_assessment jitter = 0.1 display_name = age at assessment [regression.nonverbal_iq] instrument_name = common measure_name = nonverbal_iq jitter = 0.1 display_name = nonverbal iq [regression.] ------------------------------ Each regression is configured by a section with a name such as ``[regression.]``, where ``regression_name`` is a user-selected name for the regression. The key-value pairs of a regression section are as follows. instrument_name _______________ .. code-block:: ini instrument_name = This is the name of the instrument to which the regressor (or exogenous/independent) measure belongs to. It can be left empty to indicate that the measure is present in all instruments. measure_name ____________ .. code-block:: ini measure_name = This is the name of the regressor measure. jitter ______ .. code-block:: ini jitter = A float value that determines the amount of jitter to apply to points when drawing the regression plot. The default value is 0.1. display_name ____________ .. code-block:: ini display_name = Determines the name of the regression's column in the phenotype browser.
