In order to assess the performance of the prediction method, the predicted median estimates using our method were compared to these "true" medians (i.e., observed median estimates using data as of December 31 , 2001 for the study sample.
A graphical comparison was made between observed data and the model predicted median and 95% prediction interval over time.
Again, we can derive model-based predictions: overall, patients allocated to receive adjuvant chemotherapy had a predicted median survival time of approximately 16 months, as opposed to 8 months among those treated with radiotherapy alone.
The predicted median age in the United States in 2030 is 39 — against 43 in China, 44 in Russia, 49 in Germany and 52 in Japan.
Our objective was to quantify the effect of different statistical techniques, inclusion/exclusion criteria, and missing data on the predicted median survival age.
With enhanced screening and implementation of new therapies the predicted median survival for newborns in 2000 with CF is likely more than 50 years [6].
The results show that if ϵ is neglected in the considered simulations, then the predicted median structural capacities is decreased by around 10%, 15%, and 18%, respectively, for the three abovementioned hazard levels.
Table 7 Predicted median pH and NO3 concentration in the root zone for the distinguished vegetation structure types on all soil types in 1990, 2010 and 2030 in response to combined deposition and hydrology scenarios Soil type 1990 2010 2030a II BB IB BI pH Sand poor 3.98 4.07 4.05 4.05 4.05 4.06 Sand rich 4.01 4.12 4.10 4.11 4.10 4.11 Sand calc.
The inflation factor was calculated by dividing the observed median of the statistics trend tests by the predicted median of the χ2 statistics of 0.456 if inflation is absent.
We also found that the difference of actual and predicted median age on the same group of subjects (between 5 and 6 subjects in the 20% partition) by cross validation is between 5.41 and 8.83 years.
Predicted median survival is 19 months.
