1. A method in a host organization having at least a processor and a memory therein to execute instructions, the method comprising: receiving a request at the host organization from a user device to display a tabular dataset; retrieving the tabular dataset from a database system executing at the host organization; displaying the tabular dataset as output to the user device, the displayed output including a plurality of data values depicted as known values and a plurality of null values depicted as unknown values; receiving input from the user device to populate the tabular dataset to a specified fill percentage; querying the database system for predicted values to populate a portion of the null values of the tabular dataset, wherein querying the database system comprises issuing a PREDICT command term and passing as a parameter one or more specified columns of the tabular dataset to be predicted; receiving a distribution for every one of the plurality of null values within the tabular dataset responsive to querying the indices for the predicted values; calculating a credible interval for each distribution received; populating the portion of the null values of the tabular dataset with the predicted values until the specified fill percentage is reached; and displaying the tabular dataset having the predicted values populated therein as updated output to the user device by displaying selected ones of the predicted values that correspond to a calculated credible interval in excess of a minimum threshold.
