DEFINITION
Warehousing and storage, Chain-type Quantity Indexes (2000 = 100) A quantity index is an index number that measures the change in the level of a quantity from a base year, apart from anychanges in relative prices. The value of the quantity index is 100 for the base year.The Bureau of Economic Analysis uses chain-type annual-weighted indexes, also known as Fisher indexes, as its measure of realoutput and prices. These measures allow for the effects of changes in relative prices and in the composition of output overtime, thereby eliminating a major source of bias inherent in fixed-weight indexes.
A correlation is a statistical measure of similarity between at least two given sets of data. StateMaster's
correlations compare two variables from our database and reveal statistical relationships between them. The percentages
you see represent the strength (or likelihood) that a change in the topic variable is matched by a change in the listed
variables below it. But remember: These correlations do not imply causation, that is, one does not necessarily cause
the other. Also, not all variables contain all states, rather subsets of states matched together.
Outliers have been removed only where they are outside 3 standard deviations of the mean.
Only variable pairs where at least 15 states match for each have been considered.
Strength is given by the correlation coefficient (R squared). It is the fraction of variation in Y that can be attributed to the variation in X. 100% signifies a perfect fit (R squared of 1). The top 50 such stats are displayed
