Oh, dude, the persistence method of forecasting is limited because it just blindly assumes that the future will be exactly like the past. Like, come on, life isn't a rerun of yesterday's sitcom. It's like trying to predict the weather by looking out the window and saying, "Yep, it's sunny now, so it'll be sunny forever." So yeah, it's limited because it doesn't account for any changes or surprises that might pop up.
persistence
A method that uses the effect of past weather conditions in forecasting is called persistence forecasting. This method assumes that the weather conditions at a given time will remain the same as the recent past. It is a simple and often reliable technique, especially for short-term forecasts.
The forecasting method that uses the data from the same date in previous years to predict today's weather is known as climatological or climatic forecasting. This method relies on historical weather patterns and averages to make predictions for specific dates in the future.
Three methods commonly used to determine the accuracy of a forecasting method are Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE). These metrics compare the forecasted values to the actual observed values, providing a numerical measure of the forecasting method's accuracy.

Judgmental forecasting is the oldest and still the most important method of forecasting the future.
The Climatology method uses averages to predict future weather by relying on historical climate data to establish expected conditions for a given time and location. This approach assumes that future weather patterns will closely resemble long-term averages. Other methods like Trends, Persistence, and Analog focus on different aspects of weather patterns and do not primarily utilize historical averages.
There are many methods of sales forecasting. One method is to look at what has happened in the past and based on that, predict the future.
