# Views (Risk and Correlation)

The users may enter up to five different sets of views in the grid. To select a set of expected risk and correlation (covariance) model for analysis, click on the column heading to highlight the column.

The user will be able to initialize a custom view by copying from the historical full-sample estimates.

When specifying views for risk, it is also essential to carefully consider the specification of correlation coefficients. If a correlation matrix is not positive semi-definite, WPA can either correct to the nearest positive semi-definite matrix or re-initialize the respective view estimates to the historical correlation matrix.
