[Classification of multidimensional observations using linear discriminant functions].

In the present paper the role of linear discriminant analysis is delimitated all along with a range of problems which could be solved using this method in appropriate conditions. The analysis is given of possibilities on how to involve the decrease in number of variables in a model, and how to predict probability of incorrect classification. As an example of application, the prediction of dog survival is calculated in radiobiological experiment on the basis of biochemical and hematological values which were obtained by the 2nd day after the irradiation as well as an error probability was determined.

Discriminant Analysis

Effects of neutron and combined gamma irradiation of rats.

The effect of single neutron irradiation (2 Gy) alone and combined with continuous gamma irradiation (6 Gy accumulated during 10.5 days) was studied on the survival of rats and on nucleic acids both in the lymphoid organs and testes. After neutron irradiation alone the most profound changes in lymphoid organs and testes were found on the third and within the days 28-60, respectively. Regeneration has been undergone at a relatively fast rate. Continuous irradiation subsequent to neutron irradiation deepened only slightly the extent of the initial changes. The effect of combined irradiation manifested mainly a later times in marked slowing down of regeneration.
