Generalized analysis of variance |
Generalized analysis of variance (GANOVA) helps to assess extent to which a selected numeric response variable is influenced by (a) qualitative factors (as name of operator, workshift, number of production line, raw material supplier, etc.) and/or (b) quantitative numeric variables (as temperature, pressure, mixer revolutions). The response variable of interest may typically be a quality parameter or any process or experimental output. As such, this module is useful for spotting how to influence or stabilise an important output parameter, to identify and prove influence of certain factors on important output and consequently eliminate or stabilise the influential factors to stabilise or improve quality.
