(21) The corresponding R-squared values, or explanatory power, of the models in Table 3 are lower than in Table 2, and range from 0.0818 to 0.2410.
This is why the single or multivariate models with or without change-points (Models 1, 2, and 3) produce very poor results with the very low R-squared values shown in Table 2, specifically for Buildings 1, 2, and 3 that have more different data clusters.

Input: Stipulated number of iterations I, current number of iterations i, previous retrieval equation [y.sub.1](x), current retrieval equation [y.sub.2](x), and corresponding R-squared values [R.sub.1] and [R.sub.2] Output: Target retrieval equation y(x) (1) Designate retrieval weight, with 1 g as sampling point, retrieval from 5 g to 15 g; (2) Calculate retrieval equation [y.sub.1](x) using LSR (Eq.
Bivariate r-squared values were calculated using Statistix 9 analytical software (Statistical Software, Tallahassee, FL) for indicating the predictive power of the independent variables relative to the level of injury from an H-ARS RC3 condition.
Table 5 summarizes the full model, which resulted in an R-Squared value of .087.
R-squared values for the load-displacement curves from experiment and the simulations adopting different stress-strain curves.
However, it is worth noting that the R-Squared value obtained when using actual hurricane variable (data) is significantly higher when compared with the R-Squared value obtained using the predicted hurricane variable, which appears in Table 5 and Table 6.
The R-squared value is not very high for the model (60%) due to characteristics of the sample however; regression model is highly significant (Probability .
In each case, third order polynomial trend lines were used to fit the data, and the R-squared value for the fit is indicated on the graphs.
