What does KMO mean in UNCLASSIFIED
KMO stands for Kaiser Meyer Olkin, which is a measure of sampling adequacy used to assess the suitability of data for factor analysis. It provides an indication of whether or not the variables in a dataset are suitable for exploratory factor analysis. KMO is an important tool when conducting factor analysis as it can be used to determine if the correlation among the variables is strong enough to warrant further exploration. Generally, a higher KMO value indicates that the dataset is more suitable for exploratory analysis than one with a lower score.

Background Information
KMO was first proposed in 1970 by American psychologists Albert L. Kaiser and Martin O. Mero, and statistician Samuel D. Olkin and developed into its current form by Stanley Mulaik in 1975. The measure is calculated to offer an understanding of how correlated each variable is with every other and whether factor analysis should be attempted on them or not. The formula looks at correlations between individual items on a survey and uses this information to generate an overall figure that can then be interpreted depending upon how much correlation exists between each item.
How KMO Works
To calculate KMO, two kinds of inter-item correlation matrices are needed; partial matrices (which measure the degree of association among pairs of variables) and total matrices (which measure total association among all variables). These matrices are usually generated using Pearson's Correlation Coefficient (r). The pairwise correlations in both partial and total matrices are then compared using KMO, which looks at whether there are strong positive or negative associations between any two items on a survey or set of surveys across multiple participants, since this will indicate how likely it is that factor analysis will yield meaningful results.
Interpretation Of Results
The result from the calculation of KMO can range from 0 to 1 with values greater than 0.5 indicating that enough correlations exist between all items so that factor analysis may be useful in exploring relationships among them. A value less than 0.5 indicates that there was insufficient inter-item correlation present so exploring these relationships with factor analysis may not be necessary or beneficial.
Essential Questions and Answers on Kaiser Meyer Olkin in "MISCELLANEOUS»UNFILED"
What is Kaiser Meyer Olkin (KMO)?
KMO is a measure used to assess the sampling adequacy of correlation matrices, which are used to analyze the relationship between variables. It is calculated as the proportion of variance among variables that can be explained by common factors extracted from the correlation matrix
Final Words:
In summary, KMO (Kaiser Meyer Olkin) is a calculation which measures the suitability of data for exploratory factor analysis and helps inform decisions about whether to use factor analysis as part of research methodology or not. A high value indicates good potential for successful outcomes from exploratory data mining tools such as factor analysis whereas low values suggest further exploration may not yield meaningful results.
