A health utility value of 1.00 indicates perfect health while a score of 0.00 indicates death. Negative values account for the fact that some health states are identified by the general public as being worse than death. To calculate a health utility score, health states for each response are converted using a look-up table and mathematical formula.
The quality-adjusted life year (QALY) is a generic measure of disease burden, including both the quality and the quantity of life lived. [1] [2] It is used in economic evaluation to assess the value of medical interventions. [1] One QALY equates to one year in perfect health. [2] QALY scores range from 1 (perfect health) to 0 (dead).

Churn rate (also known as attrition rate, turnover, customer turnover, or customer defection) [1] is a measure of the proportion of individuals or items moving out of a group over a specific period. It is one of two primary factors that determine the steady-state level of customers a business will support.
The Quality of Well-Being Scale (QWB) is a general health quality of life questionnaire which measures overall status and well-being over the previous three days in four areas: physical activities, social activities, mobility, and symptom/problem complexes. [1] It consists of 71 items and takes 20 minutes to complete. [2]
If the null hypothesis is true, the likelihood ratio test, the Wald test, and the Score test are asymptotically equivalent tests of hypotheses. [8] [9] When testing nested models, the statistics for each test then converge to a Chi-squared distribution with degrees of freedom equal to the difference in degrees of freedom in the two models.
An alternative motivation theory to Maslow's hierarchy of needs is the motivator-hygiene (Herzberg's) theory. While Maslow's hierarchy implies the addition or removal of the same need stimuli will enhance or detract from the employee's satisfaction, Herzberg's findings indicate that factors garnering job satisfaction are separate from factors leading to poor job satisfaction and employee turnover.
Session success rate measures the ratio of user sessions that lead to a success. Defining "success" is often dependent on context, but for search a successful result is often measured using dwell time as a primary factor along with secondary user interaction, for instance, the user copying the result URL is considered a successful result, as is ...
