Correcciones Aplicadas: Escribir Resultados en Excel
**Fecha**: 2025-11-09
**Commit**: ed06bc0
**Estado**: β
**COMPLETADO Y DESPLEGADO**

## π Problema Identificado
El usuario reportΓ³ que solo la funciΓ³n **Univariate Forecast** escribΓa resultados en Excel, mientras que las demΓ‘s funciones solo mostraban informaciΓ³n en el log.
### AnΓ‘lisis del CΓ³digo
**FunciΓ³n que funcionaba correctamente:**
- β
`forecastUnivariate()` - Usaba `writeForecastResults()` para escribir tabla formateada
**Funciones con problemas (solo mostraban en log):**
- β `detectAnomalies()` - LΓnea ~340
- β `runBacktest()` - LΓnea ~390
- β `forecastMultiSeries()` - LΓnea 459: "simplificado - solo mostrar en log"
**Funciones nuevas (ya escribΓan correctamente):**
- β
`forecastWithCovariates()` - Ya tenΓa cΓ³digo de escritura
- β
`generateScenarios()` - Ya tenΓa cΓ³digo de escritura
- β
`forecastMultivariate()` - Ya tenΓa cΓ³digo de escritura

## π§ Correcciones Aplicadas
### 1. detectAnomalies() - CORREGIDO β
**Antes:**
```javascript
const anomalyCount = data.anomalies.filter(a => a.is_anomaly).length;
if (anomalyCount > 0) {
log(`β οΈ Found ${anomalyCount} anomalies!`, 'error');
data.anomalies.filter(a => a.is_anomaly).forEach(a => {
log(` Point ${a.index}: value=${a.value.toFixed(2)}, expected=${a.predicted_median.toFixed(2)}`);
});
} else {
log('No anomalies detected β', 'success');
}
```
**DespuΓ©s:**
```javascript
const anomalyCount = data.anomalies.filter(a => a.is_anomaly).length;
if (anomalyCount > 0) {
log(`β οΈ Found ${anomalyCount} anomalies!`, 'error');
} else {
log('No anomalies detected β', 'success');
}
// Escribir resultados en Excel
await Excel.run(async (context) => {
const selection = context.workbook.getSelectedRange();
selection.load('rowIndex, rowCount');
await context.sync();
const startRow = selection.rowIndex + selection.rowCount + 2;
const sheet = context.workbook.worksheets.getActiveWorksheet();
// Preparar datos
const tableData = [['Index', 'Value', 'Expected', 'Lower', 'Upper', 'Is Anomaly']];
data.anomalies.forEach(a => {
tableData.push([
a.index,
parseFloat(a.value.toFixed(2)),
parseFloat(a.predicted_median.toFixed(2)),
parseFloat(a.lower.toFixed(2)),
parseFloat(a.upper.toFixed(2)),
a.is_anomaly ? 'YES' : 'No'
]);
});
const range = sheet.getRangeByIndexes(startRow, 0, tableData.length, 6);
range.values = tableData;
range.format.autofitColumns();
// Format header
const headerRange = sheet.getRangeByIndexes(startRow, 0, 1, 6);
headerRange.format.font.bold = true;
headerRange.format.fill.color = '#4472C4';
headerRange.format.font.color = 'white';
// Highlight anomalies in RED
for (let i = 0; i < data.anomalies.length; i++) {
if (data.anomalies[i].is_anomaly) {
const anomalyRange = sheet.getRangeByIndexes(startRow + i + 1, 0, 1, 6);
anomalyRange.format.fill.color = '#FFC7CE';
}
}
await context.sync();
});
log('β¨ Anomaly results written to spreadsheet', 'success');
```
**Resultado:**
- Tabla con 6 columnas: Index, Value, Expected, Lower, Upper, Is Anomaly
- Header con fondo azul
- AnomalΓas destacadas en ROJO (#FFC7CE)
---
### 2. runBacktest() - CORREGIDO β
**Antes:**
```javascript
const metrics = data.metrics;
log(`π Backtest Results:`, 'success');
log(` MAE: ${metrics.mae.toFixed(2)}`);
log(` MAPE: ${metrics.mape.toFixed(2)}%`);
log(` WQL: ${metrics.wql.toFixed(3)}`);
// Interpretar resultados
if (metrics.mae < 5) {
log(' Quality: Excellent βββββ', 'success');
} else if (metrics.mae < 10) {
log(' Quality: Good ββββ');
} else {
log(' Quality: Moderate βββ');
}
```
**DespuΓ©s:**
```javascript
const metrics = data.metrics;
log(`π Backtest Results: MAE=${metrics.mae.toFixed(2)}, MAPE=${metrics.mape.toFixed(2)}%`, 'success');
// Escribir resultados en Excel
await Excel.run(async (context) => {
const selection = context.workbook.getSelectedRange();
selection.load('rowIndex, rowCount');
await context.sync();
const startRow = selection.rowIndex + selection.rowCount + 2;
const sheet = context.workbook.worksheets.getActiveWorksheet();
// Tabla de mΓ©tricas
const metricsData = [
['Metric', 'Value'],
['MAE', parseFloat(metrics.mae.toFixed(2))],
['MAPE', metrics.mape.toFixed(2) + '%'],
['RMSE', parseFloat(metrics.rmse.toFixed(2))],
['WQL', parseFloat(metrics.wql.toFixed(3))]
];
const metricsRange = sheet.getRangeByIndexes(startRow, 0, metricsData.length, 2);
metricsRange.values = metricsData;
metricsRange.format.autofitColumns();
// Format header
const headerRange = sheet.getRangeByIndexes(startRow, 0, 1, 2);
headerRange.format.font.bold = true;
headerRange.format.fill.color = '#70AD47';
headerRange.format.font.color = 'white';
// Forecast vs Actuals si estΓ‘n disponibles
if (data.forecast_median && data.actuals) {
const forecastData = [['Timestamp', 'Forecast', 'Actual', 'Error']];
for (let i = 0; i < data.forecast_median.length; i++) {
const error = Math.abs(data.forecast_median[i] - data.actuals[i]);
forecastData.push([
data.forecast_timestamps[i] || `t+${i+1}`,
parseFloat(data.forecast_median[i].toFixed(2)),
parseFloat(data.actuals[i].toFixed(2)),
parseFloat(error.toFixed(2))
]);
}
const forecastRange = sheet.getRangeByIndexes(
startRow + metricsData.length + 2,
0,
forecastData.length,
4
);
forecastRange.values = forecastData;
forecastRange.format.autofitColumns();
const forecastHeaderRange = sheet.getRangeByIndexes(
startRow + metricsData.length + 2,
0,
1,
4
);
forecastHeaderRange.format.font.bold = true;
forecastHeaderRange.format.fill.color = '#4472C4';
forecastHeaderRange.format.font.color = 'white';
}
await context.sync();
});
log('β¨ Backtest results written to spreadsheet', 'success');
```
**Resultado:**
- Tabla de mΓ©tricas (MAE, MAPE, RMSE, WQL) con header verde
- Tabla de comparaciΓ³n Forecast vs Actual con header azul
- Columna de Error calculada automΓ‘ticamente
---
### 3. forecastMultiSeries() - CORREGIDO β
**Antes:**
```javascript
const result = await response.json();
log(`β¨ Generated forecasts for ${result.forecasts.length} series`, 'success');
// Escribir resultados (simplificado - solo mostrar en log)
result.forecasts.forEach(forecast => {
log(` ${forecast.series_id}: ${forecast.median.length} periods`);
});
```
**DespuΓ©s:**
```javascript
const result = await response.json();
log(`β¨ Generated forecasts for ${result.forecasts.length} series`, 'success');
// Escribir resultados en Excel
await Excel.run(async (context) => {
const selection = context.workbook.getSelectedRange();
selection.load('rowIndex, rowCount');
await context.sync();
const startRow = selection.rowIndex + selection.rowCount + 2;
const sheet = context.workbook.worksheets.getActiveWorksheet();
let currentRow = startRow;
// Escribir cada serie
result.forecasts.forEach(forecast => {
// Header de la serie
const seriesHeaderRange = sheet.getRangeByIndexes(currentRow, 0, 1, 1);
seriesHeaderRange.values = [[`Series: ${forecast.series_id}`]];
seriesHeaderRange.format.font.bold = true;
seriesHeaderRange.format.fill.color = '#4472C4';
seriesHeaderRange.format.font.color = 'white';
currentRow++;
// Datos de la serie
const tableData = [['Timestamp', 'Median', 'Q10', 'Q90']];
for (let i = 0; i < forecast.timestamps.length; i++) {
tableData.push([
forecast.timestamps[i],
parseFloat(forecast.median[i].toFixed(2)),
parseFloat(forecast.quantiles['0.1'][i].toFixed(2)),
parseFloat(forecast.quantiles['0.9'][i].toFixed(2))
]);
}
const dataRange = sheet.getRangeByIndexes(
currentRow,
0,
tableData.length,
4
);
dataRange.values = tableData;
dataRange.format.autofitColumns();
// Format header
const headerRange = sheet.getRangeByIndexes(currentRow, 0, 1, 4);
headerRange.format.font.bold = true;
headerRange.format.fill.color = '#D9E1F2';
currentRow += tableData.length + 1; // +1 para separaciΓ³n
});
await context.sync();
});
log('β¨ Multi-series forecasts written to spreadsheet', 'success');
```
**Resultado:**
- Una tabla por cada serie con su propio header
- Headers de serie con fondo azul oscuro
- Headers de datos con fondo azul claro
- SeparaciΓ³n entre series

commit ed06bc0
Author: Droid
Date: 2025-11-09
Fix: Write results to Excel for all functions
- detectAnomalies() now writes anomaly table with highlighted anomalies
- runBacktest() now writes metrics table + forecast vs actual comparison
- forecastMultiSeries() now writes results for each series
- All 7 functions now properly write formatted results to Excel
```
