This has allowed us to identify good practice, useful statistical methods, methodological challenges (Table 2), and some limitations in current reporting and methodology to be addressed (Table 3).
Univariate time series regression models were applied to analyse the age-specific time-course of varicella cases in the practices, following the statistical methods described by Höhle et al. [ 22].
Frequency domain extreme prediction methods may be broadly categorised as either empirical combination, such as those used in the current design codes and rules of recommended practice, or rigorous statistical methods which are based on predicting crossing rates and applying a 'correction' factor for the potential clumping of wave peaks.
There was a tendency for hospital admission dates to be close to removal dates (odds = 1.25, P = 0.008) but not to re-registration dates (odds = 1.16, P = 0.084) than could be expected by chance (a health service date was defined as close to a practice transfer date if fell in the first or last 25% of the period between two practice transfer dates; see statistical methods).
The aim of this paper is to review three leading UK journals in general practice and to see what statistical methods are being used.
– the 25th, 50th and 75th percentiles of the practice mean number of events in the first 5 years of life – see statistical methods The inter-practice relationship between prescribing and recording of diagnostic codes is displayed in Figure 1, separately for each database.
In addition, Figure 2 also indicates that the weighting approach may save hundreds of whole-genome subjects to achieve an acceptable power in practice, say 80%, compared with original statistical methods.
Papers in the BMJ and the BJGP used more sophisticated statistical methods than Family Practice (Table 4).
This review will allow us to examine current statistical methods used in practice with respect to missing outcomes in CRTs.
The least sophisticated statistical methods appeared in Family Practice.
There is an average of 10 years between the development of improved statistical methods and their implementation in practice.
