We often get questions about our logotype.

logo1 The symbol is the Greek letter t (pronounced tau). It is used to symbolize the total, ie the total of any one is interested, for example, sum of the production of a particular commodity in Sweden.


logo2 In statistical inference distinguishes between the true value and the estimated value. The estimated value is the value to guess at, for example by measure a sample. The estimated value is denoted by a caret (ceiling) above the quantity estimated. tau hat therefore means the estimated total.


logo3 The ring that tau hat comes out represents the target population being studied, such as Population or the employees of a particular company.
