  "definition": "Data transformation is a mathematical treatment which alters the measurement scale of the observations. Data are transformed to linearize data for analysis by linear regression or to alter the distribution prior to parametric analyses when data do not meet the requirements of normality and homogeneity of variance. The type of transformation necessary is determined by the type of data (count, continuous or proportion) and the direction in which the data are skewed. Kutner et al. (2004) includes several chapters which cover diagnostics and remedial measures for regression analysis.",
