Abstract
The modified chi-square method as well as the minimum chi-square method is well known as a method of estimation of parameters in a population. By referring to these methods, a new estimation method is explored which is suitable for the data consisting of a cumulative frequency. A method using appropriate variable transformation is also proposed. The application of this method enables us to reduce the problem of estimation to easier one and the estimates to the closed forms. The algorithm is described in detail, and illustrated by two examples.
