For the term disability, both categorical (for example: physical disability) and functional definitions (for example: spinal cord injuries), were used.
It is perhaps not surprising that genomic signatures tend to outperform the pre-existing clinical models when one considers the large numbers of additional factors that are being taken into account, and that precision of measurement of these factors is continuous (gene expression levels) rather than categorical (for example, tumour grade and lymph node status).
Example 2. A categorical syllogism: (This example appears in MAL, but with the letters and premises rearranged).
A multivariable regression model using NEAP as the dependent variable, and age (categorical variable; for example, 1 as the elderly and 0 as the young) as the main independent variable of interest was applied.
Student T test (+− Mann–Whitney U test) was used to compare continuous variables; for example, age and Pearson's chi-square test (with Yates'correction/Fisher's exact test) was used to compare categorical variables; for example, sex (female or male), atopic status (yes or no) between children with and without unscheduled visits.
The linear regression model is often adequate for analysis of health sector inequalities, where we simply want to predict discrete change in predicted probabilities of expenditure across the categorical variables, for example, maternity care expenditure conditional on income, age and so on.
They make a categorical distinction, for example, between objects and non-solid substances (i.e., water or sand).
Categorical data (for example, sex, ethnicity, stage, mutation frequency) were compared using a chi-squared test.
Categorical covariates, for example, gender and genotype, were modelled using indicator variables.
For example, categorical attribute values in private data sets may not appear in public data.
