A researcher developed a 5-item (Likert style 6-option per item) test that measure a single construct.  She calculated a covariance matrix of the items and fitted a unidimensional confirmatory factor analysis model.  The estimated item loadings and residual variances are shown below.  Y1 through Y5 represent items. F Lambda Resid. var. Y1 0.6 1.3 Y2 0.4 1 Y3 0.5 1 Y4 0.7 1.2 Y5 0.8 1.1 What is the value of the omega coefficient?
