This textbook survival guide was created for the textbook: Probability and Statistics for Engineers and Scientists, edition: 4.

• a-error (or a-risk)

  In hypothesis testing, an error incurred by failing to reject a null hypothesis when it is actually false (also called a type II error).

• Addition rule

  A formula used to determine the probability of the union of two (or more) events from the probabilities of the events and their intersection(s).

• Alias

  In a fractional factorial experiment when certain factor effects cannot be estimated uniquely, they are said to be aliased.

• Attribute

  A qualitative characteristic of an item or unit, usually arising in quality control. For example, classifying production units as defective or nondefective results in attributes data.

• Backward elimination

  A method of variable selection in regression that begins with all of the candidate regressor variables in the model and eliminates the insigniicant regressors one at a time until only signiicant regressors remain

• Bias

  An effect that systematically distorts a statistical result or estimate, preventing it from representing the true quantity of interest.

• Box plot (or box and whisker plot)

  A graphical display of data in which the box contains the middle 50% of the data (the interquartile range) with the median dividing it, and the whiskers extend to the smallest and largest values (or some deined lower and upper limits).

• Comparative experiment

  An experiment in which the treatments (experimental conditions) that are to be studied are included in the experiment. The data from the experiment are used to evaluate the treatments.

• Conditional probability mass function

  The probability mass function of the conditional probability distribution of a discrete random variable.

• Conditional variance.

  The variance of the conditional probability distribution of a random variable.

• Correlation coeficient

  A dimensionless measure of the linear association between two variables, usually lying in the interval from ?1 to +1, with zero indicating the absence of correlation (but not necessarily the independence of the two variables).

• Covariance matrix

  A square matrix that contains the variances and covariances among a set of random variables, say, X1 , X X 2 k , , … . The main diagonal elements of the matrix are the variances of the random variables and the off-diagonal elements are the covariances between Xi and Xj . Also called the variance-covariance matrix. When the random variables are standardized to have unit variances, the covariance matrix becomes the correlation matrix.

• Curvilinear regression

  An expression sometimes used for nonlinear regression models or polynomial regression models.

• Decision interval

  A parameter in a tabular CUSUM algorithm that is determined from a trade-off between false alarms and the detection of assignable causes.

• Deining relation

  A subset of effects in a fractional factorial design that deine the aliases in the design.

• Deming

  W. Edwards Deming (1900–1993) was a leader in the use of statistical quality control.

• Empirical model

  A model to relate a response to one or more regressors or factors that is developed from data obtained from the system.

• Finite population correction factor

  A term in the formula for the variance of a hypergeometric random variable.

• Fraction defective

  In statistical quality control, that portion of a number of units or the output of a process that is defective.

• Fractional factorial experiment

  A type of factorial experiment in which not all possible treatment combinations are run. This is usually done to reduce the size of an experiment with several factors.
