Abstract:

A series of partly empty small samples may make it difficult, when analysing ecological material, to obtain a picture giving a proper representation of the course of the phenomenon. Application of a moving average fails when the gaps (subsequences of zero samples) in the completion of the series by materiał are large and unequal (cf. Fig. 2, referring to material set out in Table II). The author suggests a method of calculating the curve by small sections formed from the various gaps which are limited on one side by a completed sample. The different sections may be formed either from single gaps or from two or three neighbouring gaps. The value of each section is defined by the arithmetical average of the values of the empty and full samples contained in it according to the formula:f[xn(k)] =(∑_(i=1`)^(n(k))▒〖f(xi)〗)/(n(k))Figs. 3 and 5 illustrate the elements of the curve calculated according to the method given for the example from Table II. They were calculated on the basis of two neighbouring gaps: n(2).
