WebNov 1, 1989 · Abstract. There exists a loss function whose expectation is minimized at mode ( y ∣ x ). Adding the assumption of mode ( y ∣ x )= x ′β, the mode regression estimator is derived. The mode regression finds its major application in the case of truncated dependent variable, particularly with asymmetric density under homogeneity. … Web1. Introduction. A mode of a probability density f(t) is a value of t which maximizes f. Relatively little attention has been paid to estimating the mode perhaps because of the delicacy of the problem: any method for estimating the mode must estimate a density, either explicitly or implicitly, and this is itself a difficult problem.

"WebIn statistics, the mode is the value that is repeatedly occurring in a given set. We can also say that the value or number in a data set, which has a high frequency or appears more frequently, is called mode or modal value.
