Statistical Analysis to Mammal Studies Based on Mammal Sleep Data
The researcher analyzes mammal sleep with 62 species in 1976 by using Lasso method (least absolute shrinkage and selection operator) that provides stability, higher selection variables, computational efficiency and higher prediction accuracy. the results of Average Parameter Estimate for using adaptive Lasso in SAS indicates that the position of slow wave and paradoxical sleep is account for 100%, overall danger index is 93%. The distributions of overall danger index and slow wave with paradoxical sleep as wee as gestation time
