Answer:

The equivalent expression is \eta^2, because respect to \omega^2 the formula is different.

Step-by-step explanation:

The equivalent expression is \eta^2, because respect to \omega^2 the formula is different.

\eta^2 "describes the ratio of variance explained in the dependent variable by a predictor while controlling for other predictors", similar to the determination coefficient.

One property is that "is a biased estimator of the variance explained by the model in the population" when we are just estimating the size effect.

And other porty is that "measures the variance explained of the sample and not the population" and many times overestimate the effect size.

The formula for is given by:

\eta^2 = \frac{SSR}{SST}

Where SST represent the total sum of squares and SSR the sum squares for the regression.

\omega^2

This one is a similar estimator to the determination coefficient, but is a estimator with lower bias. And analyze again the variance explained like the determination coefficient and the \eta^2

Since have lower bias than \eta^2 is prefered, but sometimes is not easy to calculate it. The formula to calculate is given by:

\omega^2=\frac{SS_{treatment}-(df_{treatment}*MS_{error})}{SS_{total}+MS_{error}}

There are other estimators like the Cohen's f^2 and the Cohen's q who are similar estimators to the variance explained.

Marcia has $84 less than three times as much as sue. together they have $132. how much money does marcia have?
Brut [27]
Let x = sue
and then let 3x-84 = marcia
therefore
(x)+(3x-84)=132
4x-84=132
4x=216
x=54

however just solving for x doesnt completely solve. it only shows sues money because x = sue
for marcia
3x-84
3(54)-84
162-84
78

therefore Marcia has 78$.

Find the surface area of a rectangular prism that is 16 inches long, 12 inches wide, and 5 inches high.
OverLord2011 [107]
We have an equation for the surface area of a rectangular prism:
A= 2 (w*l+ l*h+ h*w)

Plug l= 16 in, w= 12 in, and h= 5 in into the above equation, we have:
A= 2 (12 in*16 in+ 16 in* 5 in+ 5 in* 12 in)= 664 in^(2).

The final answer is 664 in^(2).

Hope this is helpful~
