| 内容記述 | The previous two papers dealt with quantitatively the process of cadets gaining skill and number of observations necessary for train to attain the applicable level as the apparentice officer (1 mile in standard error) in the meridian and ante-meridian altitude observations. The present report examined into influence of some factors which probably had effects on the accuracy of the altitude observed by cadets. The results obtained by the multiple linear regression analysis (all possible selection procedure) were summarized as follows : Relative wind direction- The influence in the ante-meridian altitude observation was expressed by the estimated multiple linear regression equation (1) and the influence in the meridian altitude observation was by the estimated equations (2) and (3). Both observations differed in the sign of partial regression coefficient. Relative wind speed- The influence in the ante-meridian altitude observation was by the estimated equations (1), (4), and (5). That in the meridian altitude observation was by the estimated equations (3) and (6). Wind wave (grade 0 to 5 in the scale of Japan Meteorological Agency) - It could be considered that there was no influence. Ship's rolling- There was no influence in the ante-meridian altitude observation. But, in the meridian altitude observation, the influence was expressed by the estimated equation (3). The times of discontinuances of training by calling foreign ports- The accuracy of the altitude observed by cadets in the ante-meridian altitude observation became stable and high as the times go by. The influence was expressed by the estimated equations (7) and (8). In the meridian altitude observation, the accuracy was almost constant, regardless of the times. | |||||
