    The article deals with the scalar-valued score function defined for any regular unimodal and continuous probability distribution with arbitrary interval support, recently introduced by the author. Function values describe the relative influence of observed values under the given model with respect to a certain 'center point' of the distribution. By means of the function is introduced a generalized moment method of parametric estimation, giving estimates with a 'natural' tradeoff between efficiency a robustness. Inference function used in the estimating equations is either the bounded score function of distribution of heavy-tailed models or its simple modification based on the Huber’s approach if the function is unbounded.
