A comparison between convenience sampling versus systematic sampling in getting the true parameter in a population: Explore from a clinical database: The Audit Diabetes Control Management (ADCM) registry in 2009

Systematic sampling is an ideal sampling technique when sampling frame is not available. Dealing with patients recruitment make convenience sampling is a choice for most of clinicians. We compare results derived from analysis of eight subsamples with the true parameter from the population based on convenience sampling with first come and first serve basis and systematic sampling. This paper discussed at what extent convenience sampling with first come and first serve basis can be a valid sampling technique in comparison with conventional systematic sampling.

Population trends in Malaysia: 1970-2010

The size of population in Malaysia had reached 28.3 million in 2010 and is expected to increase to 38.6 million in the next 30 years. This demographic milestone that is causing renewed attention to the challenges caused by population growth. This paper looks at the last 40 years of changes in Malaysia population structure due to the changes in demographic phenomenon using data obtained from the Department of Statistics Malaysia. The principal finding of this research indicates that population structure in Malaysia had changed dramatically from the year 1970 to 2010. At the same time, Malaysia has completed its demographic transition in less than four decades. The fall in fertility and mortality rates have led to an improvement in the life expectancy of the population which has resulted an ageing population in Malaysia.

Sample size guideline for exploratory factor analysis when using small sample: Taking into considerations of different measurement scales

Sample size guideline for exploratory factor analysis (EFA) was long established however none investigate the effect from the difference of measurement scales. The authors are concern if researchers prefer to use the minimum number of sample size from the guideline in conducting EFA especially in the clinical setting since it is difficult to get enough sample size. Here, the authors present a guideline of sample size requirement according to various types of measurement scales and also suggest guideline if any researcher planned to apply the rule of thumb that proposes the smallest number of sample size for EFA.

Modification of systematic sampling: A comparison with a conventional approach in systematic sampling

Systematic sampling is a nonbiased method in recruitment selection process since it is a probability sampling. However, due to slow recruitment, we modified the systematic sampling and evaluate this technique in comparison with the conventional approach of systematic sampling. In this study, we compare results derived from analysis of few sub samples, with the true parameter from the population based on modified systematic sampling and conventional systematic sampling. We found that our modified systematic sampling is slightly better than conventional approach in systematic sampling.

Malaysian Life Expectancy by Gender and Ethnic Group: A Comparative Study

The purpose of this study is to describe the Malaysian life expectancy at birth from year 1991 to 2015 by different sex and ethnic groups. Malaysia’s population shows that the life expectancy for male increased from 69.2 to 72.5 years and female also increased from 73.4 to 77.4 years within the time duration. In addition, the study found that the female life expectancy is longer than male by almost 5 years in 2015. The trend of the life expectancy for three major ethnic group in Malaysia, Malay, Chinese and Indian shows that the Chinese ethnic have longer life expectancy compared to the other two ethnics whereby Chinese females were estimated to have longer life expectancy. This comparative study may help other researcher to find out the factors that influenced Chinese females to have longer life expectancy.

Tracing Mathematical Function of Age Specific Fertility Rate in Peninsular Malaysia

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 For continuous target following under complex scene, an objective following calculation in light of multi-shading joint likelihood investigation model was introduced. The calculation embraced shading histogram to speak to the actual factual trademark with Camshaft standard and completed exploratory research in such angles as multichannel joint shading highlights measurements, projection delineate weighted preparing, the following window size and position ascertaining, calculation handling component of course. It utilised red, green, blue, tint, luminance channel shading as the objective watched attributes, and planned the computation technique given the likelihood measurement to recognise any shading focus from the compound scene. It likewise settled the counting method for following window size and position which adjusted the multi-shading model. Utilizing weighting projection outline strategy, the foundation obstruction around the objective potential territory was dispensed with. Finally, more reasonable joining judgment and the calculation cycle tenets were advanced. After the test accreditation, the ongoing execution and recognition proportion introduce a decent outcome.

Malaysia’s Ageing Population Trends

Population ageing has been on the policy agenda for over a decade, and it will become a more important policy issue in the future. Malaysia has completed its demographic transition in less than four decades. Declining in fertility and mortality rates has led to an improvement in the life expectancy of the population which has resulted an ageing population in Malaysia. The age distribution of Malaysia’s population had changed dramatically from 1970 to 2010 where the percentage of the population aged less than 20 years old had decreased by 18.3 % from 55.6 % in 1970 to 37.3 % in 2010. On the other hand, the share of elderly population (age 60 years or over) had increased from 5.5 to 7.9 % for the same period. The proportion of elderly is projected to reach 16.3 % of the total population by the year 2040. Furthermore, the old age index of Malaysia’s population has grew from 11.7 in 1970 to 28.7 in 2010. Malaysia is expected to become an ageing nation by the year 2030 where the elderly population comprises 15 % of the total population. This paper analyses ageing population trends and its changes in Malaysia. In addition, the implication of ageing population to societies and nation is also being discussed.
