The problem of setting a confidence interval for the mean of a variable on {0, 1,2} arises in three contexts: paired organ procedure rates; estimation of gene frequency, and three-point Likert scales. An effective approach to its estimation may be based on a good interval for a paired di...
Estimation of the mean of a sensitive variable in the presence of auxiliary information, Communications in Statistics-Theory and Methods 41, 1-12, 2012.Gupta, S., Shabbir, J., Sousa, R., Corte-Real, P. (2012). Estimation of the mean of a sensitive variable in the presence of auxiliary...
Mean substitution leads tobias in multivariate estimatessuch as correlation or regression coefficients. Values that are imputed by a variable’s mean have, in general, a correlation of zero with other variables. Relationships between variables are therefore biased toward zero. Standard errors and varianc...

The size of M in this dimension becomes 1, while the sizes of all other dimensions remain the same as in A. If A is a table or timetable, then mean(A) returns a one-row table containing the mean of each variable. (since R2023a) example M = mean(A,"all") returns the mean ...
A variable has a mean of 100 and a standard deviation of 12 . Four observations of this variable have a mean of 115 and a sample standard deviation of 18 . Determine the observed value of the a. standardized version of xˉ. b. studentized...
13.A variable is normally distributed with a mean of 5.00 and a variance of 4.00. Calculate the probability of observing a value of negative 0.40 or less. That is, calculate P (Xi ≤ –0.40) given X is distributed as N(5, 4). Use this excerpt from the cumulative distribution function...
The method is specifically suited for handling difficult problems posed by high-dimensional multivariate datasets (p n paradigm), such as in 'omics'-type data, among which are that the variance is often a function of the mean, variable-specific estimators of variances are not reliable, and ...
