In this paper some Totalization and Systematization of the following analyses are discussed;
(1) Multiple Regression Analysis abbreviated as MRA, which is corrected with MSD (Multiple Screw Drive) method.
(2) Principal Component Analysis abbreviated as PCA.
(3) Connected Anlysis between PCA and MRA, which is given by the name of SAPCR. SAPCR is an abbreviatted notation for Structual Analysis Type of Principal Component for Regression.
Some results of the above analysis on marine engine failure data are shown with an objective variable of Man-hour per occurrence for not only NPS but also MRA. NPS is an abbreviated notation for the Normal Probability Scale in SAPCR.
It was cleared that two variables; ratio of repair men to engine crew (X5) and total member of ship crew (X28) of the human factors affected to the results of PCA in case of the turbine tankers, and that the following variables to the results of SAPCR; the ship's ages (X9), R. P. M of main engine (X23), the automation level of ship (X24) and the evidence of failure (X15) .
