... and "Vermont" asphalt shingles have shown product weight to be a major factor in customers' perception of quality. Moreover, the weight represents the amount of raw materials being used and is therefore very important to the company from a cost standpoint. The last stage of the assembly line package ...

Using a TI-83 in Statistics
... These are the summary statistics for the frequency table. They also include the mean, standard deviation, total number, median and five number summary. Another statistic we will talk about is the interquartile range. It is gotten by performing the subtraction Q3 — Q1or 49 — 34 = 15in this example. O ...

Estimating Median Hospital Charge in the CODES Crash Outcome
... One of the variables often studied in CODES analyses is the hospital charge that was charged to each crash victim. The objective of this report is to develop a statistical technique for estimating the median of the hospital charge and other similar variables, as well as the confidence interval for t ...

A Specification Test for Linear Regressions that use
... Thus, we propose a simple specification test for logical consistency of EI–R. The test is implemented via a single linear regression using data from both the first and second stages of a proposed application of EI–R. Interpreting the results of the specification test requires consideration of only a ...

Diagnosis & Exploration of Massively Univariate fMRI Models
... We find that direct application of the CP test is not satisfactory. In simulations with a typical fMRI model (block design experimental predictors and low frequency drift basis) and white noise, we find that the CP test rejects the white noise hypothesis in excess of the nominal level. The problem i ...

Measures of Multivariate Skewness and Kurtosis
... Hence. the further the observation departs from the centroid. the larger the impact that observation has on calculating kurtosis. The observation with the largest contribution to the measure of multivariate kurtosis can be regarded as the outlier. The normalized estimate of b.p. equation (4). is the ...

The independence assumption means that the errors associated with each observation are independent from one another. For this particular example, it is the assumption that if two students are in the same region/gr ...

This break provides the possibility of day-ofthe-week eect, i.e. some weekday is dierent from other weekdays in the stoc ...
