11 11 Structure of ONS

12 12 Methodology Group Aims: –to achieve integrated and coherent statistics across ONS –to facilitate sharing of best practice To achieve these: –work closely with business areas to achieve best use of appropriate methods, etc. –provide expertise, guidance, advice

14 14 My Experiences Project work –Vacancies Survey –Register Dynamics –Retail Sales Inquiry –New Earnings Survey –Investigation of bias from small business guarantees Produce and present reports

15 15 New Earnings Survey Redesign Survey of earnings, hours, pension arrangements Currently a 1% sample of NI numbers in PAYE schemes From 2004 survey will –be stratified –include non-PAYE jobs (low pay) –have results weighted –include standard errors for all estimates

16 16 NES Redesign - Sample Design Find which variables are best correlated with earnings Propose to stratify by occupation, sex, ageband, workplace region Relies on previous data for some information Post-stratify for calculation of results

17 17 NES Redesign - Estimation Estimates will be weighted to account for non- response - design weights: a i = N h(s) / n h(s) Calibrate using LFS employee totals - calibration weights: g i = N h(ps) /  j in h(ps) a j Weighted estimate of mean: mean ( y ) =  s a j g j y j /  s a j g j

18 18 NES Redesign - Standard Errors Aim to publish standard errors with all estimates New methodology to estimate standard errors of weighted quantiles (based on estimation of the density) Software: –Generalised Estimation System (GES) and SAS
