About 68% of values drawn from a normal distribution are within one standard deviation σ away from the mean; about 95% of the values lie within two standard deviations; and about 99.7% are within three standard deviations. This fact is known as the 68-95-99.7 (empirical) rule, or the 3-sigma rule.. More precisely, the probability that a normal deviate lies in the range between − and + is

Stata arbejder med tre forskellige filtyper og de genkendes på baggrund af deres ekstension, dvs. det de ender på. Stata filtyper: Nel caso di una variabile casuale normale, =, così che il coefficiente di curtosi risulta pari a zero. Se il coefficiente di curtosi è: > 0 la curva si definisce leptocurtica , cioè più "appuntita" di una normale.

Stata has four flavors: Small, Intercooled (Standard), Special Edition (SE), SE for multiprocessor (MP). In UNIX, type in "stata -b do file_name" to run Stata in the non-interactive mode. 2018-01-18 2012-07-18 Defining the number of decimal values means defining the maximum number of decimal values displayed, whereas not defining the number of decimal values will make Stata display as many decimal places as are present, within the limits of the overall width of … In Stata use the command regress, type: regress [dependent variable] [independent variable(s)] regress y x. In a multivariate setting we type: regress y x1 x2 x3 … Before running a regression it is recommended to have a clear idea of what you are trying to estimate (i.e.
