Multiple regression analysis was used to determine what degree of relationship, if any, existed between NS-20 failures and several combinations of environmental factors. The search was extended to determine whether or not a relationship existed between external environmental factors and the failure of subcomponents of the NS-20, i.e., the Digital Computer Unit (DCU) and the Pendulous Integrating Gyroscopic Assembly (PIGA). Environmental conditions existing at the time of failure and prior to the time of failure were included. 收起
