ing based on the density power divergence for simple null hypotheses. In this paper we extend, in a nontrivial way, the problem for composite null hypotheses in general populations. To do that we have introduced the minimum density power divergence estimator restricted to a general null hypothesis, the restricted minimum density

One hundred twelve men had low bone mineral density by either or both screening methods. Seventyone of these 112 men were tested by dualenergy xray absorptiometry and 73% had low bone mineral density. The positive protective value of the Osteoporosis SelfAssessment Tool was 73% and for quantitative ultrasound was 88%.
