Two score estimation methods are available in IRT: Maximum Likelihood (ML) and Bayesian estimation [ 19].
The use of fibrates (a proxy for treated hypertriglyceridaemia), however, was included in the hdPS score estimation.
Thus all final scoring estimations were stratified into four categories: −, 0% of stained cells; +, <20% weakly to moderately stained cells; ++, 10 20% intensively stained cells and 20 50% weakly stained cells; and +++, 20 50% positive cells with moderate-to-marked staining or >50% positive cells.

For the MOS score estimation, the codec used must be considered.
From the propensity score estimation, groups including coordinated and non-coordinated farms that share similar observable characteristics are generated, making sure that each group benefits the balancing property.
(2009) and An (2010) is that the posterior distribution of the propensity score may be affected by the outcome variable that are observed after treatment assignment, resulting in biased propensity score estimation.
This table reveals that the resulting pseudo-R2 from the propensity score estimation is low, suggesting a successful match.28 In general, Table 5 shows reassuring values for both income and employment in most of the subsamples analyzed.
Rubin (1985) argued that because propensity scores are, in fact, randomization probabilities, a Bayesian approach to propensity score analysis should be of great interest to the applied Bayesian analyst, and yet propensity score estimation within the Bayesian framework was not addressed until relatively recently.
Once a propensity score estimation is computed, the next step is to match the treated (vertically coordinated farms) to a control group (non-coordinated farms) based on the estimated propensity score (Lombardi et al. 2015; Pascucci et al. 2016; Caracciolo and Furno 2017).
