Language: English Contract No.: W-7405-ENG-36 The problem of multiple regression analysis where the dependent and independent variables are components of a two dimensional vector is discussed, and a complete statistical development of the solution of estimators for the parameters in the model is given. The theory regarding predictions and confidence statements about such predictions is also developed. A computer code was written for the IBM 704 computer which solves the above problem and a description of the code is given. The statistical model was applied to a meteorological problem in wind ‘ forecasting at the Eniwetok Proving Ground, and prediction equations were developed and evaluated.

The travel times of transverse waves are 4 to 5 sec higher. The corrections for longitadinal waves are based on the absence of a granite layer in the Pacific Ocean, while for the transverse wave it must be related to the value of the travel rate of S waves in the upper layer.

The highest levels of beta radioactivity of algae collected after the detonation of a nuclear device (Nectar) were in algae from those islands closest to the site of detonation and in the downwind path of the fallout. With time after detonation, the decline of radioactivity in the algae at Belle Island was faster than can be accounted for on the basis of physical decay alone. sand collected in the deeper waters In March 1955, (20 to 140 feet) algae and bottom of the lagoon, one half to two miles offshore, contained as much or more radioactivity than samples collected in the shallow water near shore. The radioactive decay rates of algae samples collected from Leroy and Henry Islands were greater than those of algae from other islands, indicating that there was less residual contamination from previous detonations at these two islands. Study of the radioactive decay rates of the algae at Belle Island showed
