Our focus was to assess whether SMILEY could generate biologically relevant hypotheses of missing reactions in human metabolism rather than produce a detailed list of missing enzyme functionalities.
The principal drawbacks of stepwise selection include biases in parameter estimation and reported p-value, inconsistencies among model selection algorithms, an issue of multiple hypotheses testing, and the possibility of missing the optimal model.
In addition, the use of modelling and simulation tools may permit further, the formulation of hypotheses on missing components and interactions which, after a process of reiterative computer simulation, can guide future experimentation.
According to our hypothesis of a "missing link between cytokinin signaling and plant immune regulators," we integrated two large-scale omics data sets: interactome (cellular PPI) and transcriptome (genome-wide changes in gene expression) as shown in Figure 1B.
However, consistent with our hypothesis that the list of missing genes in Bgh might be incomplete, our analysis uncovered a number of protein coding genes lacking in Bgh compared to other (filamentous) fungi.
We tested the hypotheses of higher rates of missing responses among questionnaire respondents than among telephone respondents (Hypothesis 2) and of greater willingness to answer sensitive questions in questionnaires than in telephone interviews (Hypothesis 3) by Fishers exact test (two-sided for all items since both hypotheses are relevant for all items).
Sensitivity analyses showed that the various hypotheses about the distribution of missing values for BMI and duration of expulsive efforts did not change the results.
However, a recent study using SHARE rejected the hypothesis of significant correlation patterns of missing values and health care utilisation variables [43].
This study does not support our hypothesis that the substantial proportion of missing heritability for RA can be inferred from rare coding variants.
We were unable to test our convergent validity hypothesis about conflict of interest because of missing data in the systematic reviews and primary studies.
