variable values, and a-1 ~ The correlation coefficient shows the correlation strength. 0 indicates no correlation.Covar_pop returns the population covariance of a pair of expressions. Covar_samp, returns the sample covariance of a pair of expressions. Count to accumulate events in the group. If * or some non-null constants are specified, Count counts all rows. If an expression is specified, Count returns the Count of non-null values in the expression

microelectrode filled with 2 M NaCl (1-3 mV at 12 kHz) was placed in the contralateral CA1 region (3.0mm posterior to the Bregma, 2.0mm lateral, and 1.0-1.5mm ventral ). The stimulating electrode was adjusted until a stable and maximal population spike was submit (increasing stimulation strength beyond this 'maximal 'voltage produced no further limit in spike potential ampltial ). single, 100 MS long square wave pulses were then delivered at 1 minin

A biologist experimenting with DNA modification of bacteria has found a way to make bacterial colonies sensitive toSurrounding population density. By changing the DNA, he is able to �� program �� the bacteria to respond to the varying densities in their immediate neighborhood. The culture dish is a square, divided into 400 smaller squares (20x20 ). population in each small square is measured on a four point

Simple Case functions are relatively simple in writing, but compared with Case search functions, there are some functional limitations, such as writing Case functions.Note that the Case function returns only the first value that meets the condition, and the res

Section 3 basic SELECT commands The select command or statement is used to obtain record information in one or more tables. It is generally used with the where clause to obtainIf no where clause exists, all records are returned. The general usage is as follows: SELECT attribute-listFROM table-nameWHERE condition Attribute-list: list of returned content, separated by commas. The content here can be a field, containing the expression of the fieldOr more complex subqueries. Table-name: name of a ta

Before introducing the group by and HAVING clauses, we must first talk about a special function in SQL: aggregate function, such as SUM, COUNT, MAX, and AVG. The fundamental difference between these functions and other functions is that they generally work on multiple records. Select sum (population) FROM bbc SUM is used in the population field of all returned records. The result is that onl

, do not believe it, try the 34 factorial to calculate what it is, kiss, if the wallet has so much money that should be good. Fortunately, Darwin summed up an uncertain truth in the natural world, that is, biology completes evolution through the natural selection process of survival of the fittest. This process looks like a bunch of random and uncertain minor changes, so that the definite and significant changes to the advantage continue. Who is strong, who has the right to speak, resources shou

expectations and variances. Taking the denominator n-1, the expectation of the sample variance is equal to the population variance, i.e. the sample variance of this definition is the unbiased estimate of the population variance. Simple to understand, because the variance is used to mean, so the degree of freedom is less than 1, is naturally divided by (n-1).Can not understand the words, image a little, for
