(Dul, J. 2016. Necessary Condition Analysis (NCA). ''''Logic and Methodology of ''Necessary but not Sufficient'' causality." Organizational Research Methods 19(1), 10-52) . NCA identifies necessary (but not sufficient) conditions in datasets, where x causes (e.g. precedes) y. Instead of drawing a regression line ''''through the middle of the data'''' in an xy-plot, NCA draws the ceiling line. The ceiling line y = f(x) separates the area with observations from the area without observations. (Nearly) all observations are below the ceiling line: y <= f(x). The empty zone is in the upper left hand corner of the xy-plot (with the convention that the x-axis is ''''horizontal'''' and the y-axis is ''''vertical'''' and that values increase ''''upwards'''' and ''''to the right''''). The ceiling line is a (piecewise) linear non-decreasing line: a linear step function or a straight line. It indicates which level of x (e.g. an effort or input) is necessary but not sufficient for a (desired) level of y (e.g. good performance or output).
