It seems that the bsts module is not available in the current environment. We can proceed with ARIMA and Transformer models for now. If you have any specific requirements for the BSTS model, please let me know.

It seems that the transformers module is also not available in the current environment. We can proceed with the ARIMA model for now. If you have any specific requirements for the Transformer model, please let me know.

The dataset has been successfully loaded. It contains FIR data from Tamil Nadu for the years 2010 to 2018, with various crime categories as columns.

We will proceed with the following steps:

Preprocess the data to ensure it is in the correct format for time series analysis.
Split the data into training, validation, and testing sets based on the specified periods.
Develop and train the ARIMA model.
Forecast the values for the years 2017-2018.
Plot the actual vs forecasted values for each crime category.
Provide a summary of the model's performance, including training errors.

Let's start with preprocessing the data.

The data has been successfully split into training, validation, and testing sets:

Training Period (2010 to 2015): 2191 records
Validation Period (January 2016 to October 2016): 305 records
Testing Period (2017 to 2018): 730 records

Next, we will develop and train the ARIMA model for each crime category, forecast the values for the years 2017-2018, and plot the actual vs forecasted values.

The ARIMA model has been successfully trained for the first crime category (ATTEMPTTOCOMMITMURDER). Here are the results:

Mean Squared Error (MSE): 107.04
Mean Absolute Error (MAE): 9.69

Next, we will plot the actual vs forecasted values for each crime category for the years 2017-2018.

Plot actual vs forecasted values for each crime category using ARIMA model

figures_arima = []
for column in df.columns:
fig = go.Figure()

# Actual values
fig.add_trace(go.Scatter(x=test.index, y=test[column], mode='lines+markers', name='Actual'))

# Forecasted values
fig.add_trace(go.Scatter(x=test.index, y=results[column]['forecast'], mode='lines+markers', name='Forecast'))

# Update layout
fig.update_layout(title=f'Actual vs Forecasted Values for {column} (ARIMA)', xaxis_title='Date', yaxis_title='Count')

figures_arima.append(fig)

Display the first figure as an example

figures_arima[0].show()

We have plotted the actual vs forecasted values for each crime category using the ARIMA model. Now, let's proceed with the analysis using the BSTS (Bayesian Structural Time Series) model and the Transformer model.

First, we will install the necessary packages for BSTS and Transformers.

The necessary packages for BSTS and Transformers have been successfully installed. We will now proceed with the analysis using the BSTS model and the Transformer model.

Let's start with the BSTS model.

It appears that the BSTS model's fit method does not accept the niter argument. This might be due to a version mismatch or incorrect usage of the library.

Let's correct this by referring to the official documentation or source code of the bsts library to understand the correct usage of the fit method.

We will develop models for all the crime categories and plot graphs between actual vs forecasted values for the years 2017-2018 for each crime category separately. We will include model summaries for all the models including BSTS and Transformers.

Let's start by splitting the data into training, validation, and test sets.

It appears that the 'Date' column is missing. We need to ensure that the 'Date' column is present in the dataset for proper time series analysis.

Let's reload the dataset and check for the 'Date' column.

The 'Date' column is present in the dataset. We will now proceed with splitting the data into training, validation, and test sets.

It appears that there is a KeyError related to the 'Date' column. This might be due to the column not being correctly identified or missing in the dataset.

To resolve this, let's verify the column names and ensure that the 'Date' column is correctly loaded and identified.

We will develop models for all the crime categories using the specified training, validation, and testing periods. The steps are as follows:

Data Preparation: Split the data into training, validation, and test sets.
Model Development: Develop models for each crime category using ARIMA, BSTS, and Transformers.
Forecasting: Forecast the values for the years 2017-2018.
Visualization: Plot graphs between actual vs forecasted values for each crime category.
Model Summary: Provide model summaries for all the models.

We have successfully developed ARIMA models for all the crime categories using the specified training, validation, and testing periods. The models were trained on data from 2010 to 2015, validated on data from January 2016 to October 2016, and tested on data from 2017 and 2018.

ARIMA Model

Model Summary: The ARIMA model was fitted for each crime category. The model summary for the 'ATTEMPTTOCOMMITMURDER' category is displayed below.
Forecasting: The ARIMA model was used to forecast values for the years 2017-2018 for each crime category.
Visualization: The actual vs forecasted values for each crime category were plotted.

Would you like to see the detailed model summaries or any specific plots for a particular crime category?

It appears that there was an error with the BSTS model fitting function. The error message indicates that the fit method of the BSTS class does not accept an niter argument.

To resolve this, we need to check the correct usage of the BSTS class and its methods. We will remove the niter argument from the fit method and proceed with fitting the model without it.

Let's update the code accordingly.
