Since AHY was a scale (continuous) variable, the algorithm employed F test for significance control of the effective independent variables in the CHAID algorithms.
In the statistical modeling of the survey, CHAID, Exhaustive CHAID, CART, MARS algorithms and MLP, a type of ANN, were compared in terms of their predictive performance in AHY as described by Ali et al.
Where, Yi is the actual AHY value of ith beekeeping farm, Yi is the predicted AHY value of ith beekeeping farm, Y is mean of the actual AHY values of beekeeping farms, Iui is the residual value of ith beekeeping farm, Iu is mean of the residual values, k is number of independent variables found significantly in the model, and n: total sample size.
We have primarily documented the comparison of three data mining algorithms in the prediction of AHY by means of some independent variables reported in materials and methods section.
568) kg for 85 beekeeping farms in the survey data, which was lower than the AHY amounts found by Korkmaz and Kumova (2000) (15.
The effect of WPA on AHY of Nodes 1, 2 and 4 was significant.
Average values in AHY for Nodes 7, 8, 9 and 10 were predicted to be 7.
Node 4 was divided into child and terminal Nodes 11 and 12 in respect to WPA, with the AHY averages of 4.

recorded white outer rectrices, pale belly, and "sandy brown above," which we considered to reveal AHY birds in alternate plumage.
In addition, a confirmed record of 1 vagrant Kittlitz's Murrelet in basic plumage (HY or AHY bird) was documented at Jogashima near Tokyo Bay on 28 November 2004 (Godo 2005), approximately 950 km south of the next most southern Asian record in Hokkaido and possibly related to unusual weather conditions (Carter and others 2011).
Most (75%) observations in this region were made in summer (May-August), including 1 confirmed record of AHY birds in alternate plumage (Laredo Sound - 1999).
