Renault Twingo Renault Twingo The Renault Twingo is a four passenger city car manufactured and marketed by the French automaker Renault, introduced in 1992 and currently in its third generation. The first generation Twingo (two door, front engine) debuted at the Paris Motor Show on 5 October 1992, receiving its formal market launch in continental European markets beginning in April 1993. Renault launched the second-generation Twingo (two door, front engine) in the summer of 2007 — and the third generation (four door, rear engine) debuted at the 2014 Geneva Motor Show, receiving its formal market launch in September 2014.

Latitude of the Gulf Stream and the Gulf Stream north wall index analysis was then used to find the pattern of variation common to the six longitudes. This is preferable to simple averaging of the six latitude estimates which would emphasise the eastern longitudes where the north-south movements are largest, and possibly obscure smaller but coherent north-south shifts further west. Correlation coefficients are calculated between the six time-series and the principal components are the eigenvectors of the resulting correlation matrix. (Empirical orthogonal function analysis proceeds instead from the variance-covariance matrix which again is biased to the eastern longitudes.) Each principal component is calculated as a weighted average of the standardised latitude series
