Day temperatures above 70[degree]F. during the first 30 days after planting and night temperatures below 60[degree] or above 70[degree] hastened maturity. Night temperatures in the 60''s retarded maturity. Total degree hours above 70[degree] during the first 20 days were consistently and significantly related to time to half-bloom. Predictions of time to half-bloom based on 20 temperature summation variables were not highly reliable.

The major problem as-sociated with document linkage, in general, is related to unreliability of the information used in the linkage process. This problem is also encountered in death clearance, where given the information on the California death certificate and a followup questionnaire, or information available from elsewhere;the public health statistician must determine which pieces of information on the 2 documents can be used to identify the individual in question. Secondly, he has to decide whether the 2 documents represent the same individual. In such follow-up studies, one is faced with the problem of matching thousands of documents. Since it takes considerable time to carry out the matching process manually, it has become necessary to seek a more economical procedure of linking documents. The program described is designed to perform document linkage on vital events. The statistical solution to the document linkage problem, when the recorded pieces of information are accurate and complete, is given by Deming and Glasser (1959). Often their theory cannot be used because the recorded pieces of information are incomplete or inaccurately recorded. Thus, the linkage on vital events performed by this program accounts for incomplete and inaccurately recorded information. The major point of interest here is the fact that the program is designed to process alphanumeric information, thus eliminating the need for recoding, abstracting, or altering the information from the source documents.
