In this example, the sex of the participants would be consideredcovariates, a type of variable that the researcher cannot control but that impacts an experiment's results. Using an adjusted mean is a way of compensating for the covariates: what is the effect of the activity or behavior if th...

1.The mathematical model of the least absolute sum (L1 Estimation) of correlated observations is deduced withparameter adjustmentas constraint.本文从理论上推导了约束条件为参数平差的相关观测值的一次范数最小平差(L1平差)模型,并对不同的数学实例进行了试算。 英文短句/例句 1.parameter adjustment参数平差,...
Figure 6 shows the least squares mean percentage change in TSS from baseline to week 24 for MANIFEST arm 3 and comparator studies in the weighted and unweighted analyses. In the weighted analysis, the reduction observed in MANIFEST arm 3 was >20% greater than that observed for all JAKi ...
A linear least squares trend line, created using the Excel trend line function (Red trace) shows a small temperature rise of 0.09C per century which is far less than the rise claimed by AGW supporters and clearly of no concern. However, the data shown in figure 5 bears little if any res...
(I)94. The parameters were estimated by fitting this equation to the stimulus–response data with a standard Marquardt–Levenberg non-linear least squares algorithm (Matlab curve fitting toolbox). Based on the parameter estimates, the area under recruitment curve (AURC) between 80 and 180% of ...
ISS is the sum of the squares of MAIS (maximal AIS) values from the 3 most injured, arbitrary chosen body regions. For a person who suffers only one injury, an ISS over 15 cor- responds to an injury that has an AIS severity score of 4, or more. In the present study the YLDs for...
