Details of each message and how to respond
-
Cannot import data because there is only one variable.
-
Cannot perform data joining because of differences between training and evaluation data variables.
-
Data cannot be imported because it is not in a supported file format.
-
Data cannot be imported because the character encoding is not supported.
-
Data cannot be imported because there are multiple variables with the same name.
-
Data cannot be imported because there are rows with a different number of variables.
-
Data cannot be loaded because it contains data for time intervals that are not supported.
-
Data cannot be read because it contains duplicate times.
-
It is unavailable prediction types for the prediction target because of the data type and unique label counts.
-
Prediction not available due to lack of a valid license.
-
Some features are limited due to lack of a valid license.
-
The data cannot be imported because there are too many variables.
-
The data cannot be read because there is a date and time that are not within the supported time period.
-
The number of unique values contained in the variable to be predicted exceeds the number of values that can be handled by the specified prediction type.
-
The prediction model creation feature is not available due to lack of a valid license.
-
The training process cannot be performed due to insufficient data.
-
The variables in the training data and evaluation data must match exactly / The variables in the training data and prediction data must match exactly
-
There is too little data in the evaluation data that contains the correct value available for the variable you want to predict.
-
Too much missing data for the variable you want to predict.
-
Unable to read data due to a long period of no data.

Model Creation and Prediction Accuracy
I cannot click "Create Prediction Model" after selecting the variable I want to predict
Cause of the message
If there is no variable checked for “Use for model” other than the variable you want to predict, you cannot create a prediction model. When you click [Create Model], Easy Predictive Analytics creates a prediction model that predicts the value of the variable you want to predict based on a variety of information other than the variable you want to predict. Therefore, a prediction model cannot be created when there is no information available other than the variables to be predicted.
You can click [Create Model] by following the steps below.
Step 1. Go to the advanced settings screen
Step 2. Check
Step 3. Make sure that [Create Model] can be clicked.
