Why
it's important
Surveys within the rail sector are often expensive and some such as the Travelcard Diary Survey can have a major impact on revenue.
How
we can help
We have a good understanding of key concepts such as survey design, minimum sample size, confidence intervals, statistical volatility and weighting. In addition, through using statistical techniques such as regression we can help explain past and current income performance which can lead to more accurate forecasting.
Who
we've helped already:
Our experience with statistical analysis includes the following:
| • | Key methodology advisor on the ATOC Retail Mystery Shopper survey since 1999. This role involves the creation of a statistically representative sample of ticket transactions, checking data quality, the calculation of pass/fail rates using LENNON data as weights and the calculation of confidence intervals. | |
| • | Creation of the survey and weighting methodology which underpinned the 2003 Freedom Pass survey. | |
| • | Use of regression techniques to estimate own-price and cross elasticities | |
| • | Use of regression techniques to estimate elasticities to Central London Employment |
