Contributor Information Eva Pagano, Email: ti. Lognormal and GLM provide relative estimates of the effect: the cost for diabetes would be six fold that for non diabetes patients calculated with the lognormal. All authors read and approved the final manuscript. Review of statistical methods for analysing healthcare resources and costs. The Gamma model provided final estimates close to the OLS albeit in presence of a statistically significant difference both in patients with and without diabetes, determining a higher cost ratio between the two groups 4.

    SLUO Lectures on Statistics and Numerical Methods in HEP. shows a `typical' ideal distribution, the effects of this smearing, and the result of. It made perfect. in Statistical Process Control (SPC). the smearing effect for three general contribution computation The basic concept of SPC is the statistical comparison.
    Our study provides a practical example of the relevance of using appropriate methods of analyzing costs of a chronic disease. If the study is focused on the analysis of health care system for policy planning, the two-part models should be preferred, because it makes it possible to quantify the global propensity to use healthcare resources, including subjects at zero costs.

    Indeed, clinical practice differs according to the centre or the general practitioner and patient case-mix [ 9 — 11 ]. To obtain results in natural units euros, dollarsthe approach of transforming the costs in any case requires a back-transformation at the moment of interpreting results.

    The present study describes the impact of analyzing health care costs on results and conclusions in a population affected by diabetes using different statistical methods. To assess the performance of each model, the root mean square error RMSE was computed for each model.

    The cost ratios estimated from the second part of the models referred to the treated patients only. As previously described [ 14 ], the mean age of patients with diabetes was The dependent variable was set equal to 1 in any subject who incurred costs, and was set equal to 0 in any subject who incurred in 0 costs.
