If we let $\operatorname { SST } = \sum \left( y _ {i } - \bar { y } \right) ^ { 2 }$ , and $\operatorname { SSE } = \sum \left( y _ { i } - \hat { y } _ { i } \right) ^ { 2 }$ , then 1-SSE/SST is the proportion of the total variation in the observed $y _ { i}$ 's that is __________ by the polynomial model. It is called the ____________ ,and is denoted by R .

The Answer of If we let $\operatorname { SST } = \sum \left( y _ {i } - \bar { y } \right) ^ { 2 }$ , and $\operatorname { SSE } = \sum \left( y _ { i } - \hat { y } _ { i } \right) ^ { 2 }$ , then 1-SSE/SST is the proportion of the total variation in the observed $y _ { i}$ 's that is __________ by the polynomial model. It is called the ____________ ,and is denoted by R .

If We Let SST⁡=∑(yi−yˉ)2\operatorname { SST } = \sum \left( y _ {i } - \bar { y } \right) ^ { 2 }SST=∑(yi​−yˉ​)2

If We Let $\operatorname { SST } = \sum \left( y _ {i } - \bar { y } \right) ^ { 2 }$
