1. An inventory agent operating on software comprising instructions operable to cause a programmable processor to:

  • receive inventory data related to stock in an inventory, the inventory data comprising planned inventory data and actual inventory data;

    use the inventory data to calculate one or more correlations in errors between the planned inventory data and the actual inventory data;

    use the one or more correlations to estimate a probability density for one or more errors;

    calculate a predicted inventory level;

    calculate an estimated error of the predicted inventory level using the probability density; and

    adjust the predicted inventory level with the estimated error to estimate an actual inventory level.
