Estimated lifetime functions of wooden houses. Note: “Actual” indicates the actual remaining fraction calculated based on the number of existing and built wooden houses (see the “Flux data method” section). “Exponential,” “Logistic,” “Normal,” “Log-normal,” and “Weibull” represent the estimated remaining fraction based on parameters that minimize the residual sum of squares (RSS) between the actual values and the estimated values for each lifetime function.
