Abstract:

Pearson distribution family (Pearson 1895) provides approximations to a wide variety of observed distributions using the first four moments or the first three moments with a left or right boundary. Curve fitting using the Pearson distributions has been extensively applied in many fields. However, in practice, it is quite unwieldy to obtain the percentage points for the Pearson distributions when consulting the inconvenient tables of percentage points or using the out-of-date computer programs. Therefore, it is essential to have an advanced and efficient computer program to compute percentage points for the Pearson distributions. To obtain the percentage points for Pearson distributions conveniently, the present study develops a new computer program which is compatible with contemporary SAS and SPSS programs.
