 Laita-friittämisestä on tärkeää konseptia, joka on tärkeää testiä. Laita-friittämisestä kuuluu eri informaatiota, joita saadaan dataa, ja informaatiota, joita on tarpeeksi monenlaista asioista. Esimerkiksi regresson analysointi, laita-friittämisestä on tärkeää asioista, ja yksi asioista on tärkeää asioista, ja yksi asioista on tärkeää asioista. Let's take a look at the concept. Wikipedia provides you the following definitions, but instead of reading the definitions I'll explain the concept with an example. Let's say that we have example data of five observations, which get values 1, 2, 3, 4 and 5, and the mean of this observation is 3. By calculating the mean, we consume one degree of freedom, so this analysis has four degrees of freedom altogether. What the degrees of freedom here tells us että jos me tiedämmin, niin me only need to know four more numbers in the series to be able to say what the exact entire series is. So if we know that the first four numbers are one, two, three and four, we know that the mean is three, then we can know, we can say that the final number must be a five because we have consumed all our recursive freedom. So initially we have five units of information, we consume one unit by estimating the mean, which leaves us four units. If we estimate the standard deviation or variance, we consume two units of information because to calculate standard deviation we have to estimate the mean first and then we calculate the standard deviation based on the differences between these observations from their mean. So the standard deviation is 1.58, to calculate standard deviation we also have to calculate the mean. Once we know the mean and standard deviation, we only need to know three more numbers in the series to say what the remaining two are. So the idea of decrease of freedom is that once you calculate more and more stuff from the same data, then you are consuming information and once the decrease of freedom goes to zero, then you can't estimate anything from the data anymore. You have used all the information that you have.
