Cause of the message

Easy Predictive Analytics does not allow time series predicting for time intervals of less than minutes.

Solution

Prepare data with equal time intervals in units of minutes or more.
Easy Predictive Analytics can create a prediction model with the last day of the month aligned if all the time information variables for the variable you want to predict are on the last day of the month. If you have the time information variables of the variable you want to predict on the last day of the month, please check if there is any data not on the last day of the month.

Please refer to the Supported time interval in the dataset for regression (time series prediction mode).
